delivered the opinion of the Court.
The United States Constitution prohibits a court from exercising jurisdiction over a party that lacks minimum contacts with the forum. Personal jurisdiction has been described as either specific — that is, based on contacts arising from the dispute at issue — or general, predicated on a party’s “continuous and systematic” contacts with the forum. Minimum-contacts analysis is easily muddled, however, as courts frequently import contacts relevant to one type of jurisdiction when deciding the other. Additionally, courts sometimes impute contacts of related entities to each other, when mere relatedness is an insufficient basis on which to confer jurisdiction. Today, we must determine whether a Louisiana hospital, either independently or through its parent corporation, has continuous and systematic contacts with Texas. We conclude that it does not.

Factual and Procedural Background
While traveling through Louisiana on December 10, 2000, Texas resident Jajah Eddington sought medical care at MHC-Minden Hospital (“Minden Hospital”), a 159-bed acute care hospital located in Min-den, Louisiana. Medical personnel treated Eddington’s flu-like symptoms in the emergency room and advised her to consult her primary care physician if her condition did not improve. Four days later, Eddington was admitted to Good Shepherd Medical Center in Longview, Texas, where she ultimately was diagnosed with toxic shock syndrome. That infection led to her death on December 28, 2000.
DeWayne Eddington, individually and as next friend of Devvyn Eddington, and as representative of Jajah Eddington’s estate, sued Kimberly-Clark Corporation asserting product liability, breach of warranty, and negligence claims. He alleged that Eddington’s use of Kotex tampons led to the infection that caused her death. On February 28, 2003, Kimberly-Clark filed a third-party petition against PHC-Minden, L.P. (“Minden”), which owns Minden Hospital, asserting that Minden’s negligence proximately caused Eddington’s death. 1 Minden is a nonresident of Texas and a wholly owned subsidiary of Province Health Care (“Province”). Kimberly-Clark pleaded that Province, whose headquarters is in Tennessee, did business in Texas and that its forum-related acts *166 should be imputed to Minden because: (1) Province owns Minden; (2) Province and Minden share officers, directors, and “common departments or business”; (3) Province and Minden do not differentiate their operations and have failed to erect “formal barriers” between themselves; and (4) Province’s officers and directors control Minden’s policies. Minden filed a special appearance and, subject thereto, a general denial. The parties conducted extensive discovery relating to the jurisdictional issue. After a hearing, the trial court concluded it had general jurisdiction over Minden and denied the special appearance.
The court of appeals affirmed, reasoning that (1) Minden itself had “continuous and systematic contacts with Texas”; and (2) Minden and Province operated as a single business enterprise, and Minden, through Province, did business in Texas.

General Jurisdiction
The Texas long-arm statute governs Texas courts’ exercise of jurisdiction over nonresident defendants.
See
Tex. Civ. PRAC.
&
Rem.Code §§ 17.041-.045. That statute permits Texas courts to exercise jurisdiction over a nonresident defendant that “does business” in Texas, and the statute identifies some activities that constitute “doing business.”
Id.
§ 17.042. The list, however, is not exclusive.
BMC Software Belg., N.V. v. Marchand,
In
Helicópteros Nacionales de Colombia, S.A. v. Hall,
the Supreme Court adopted the terms “specific” and “general” to describe the differing types of personal jurisdiction.
Helicopteros,
*167
In
Helicópteros,
the Court concluded that Texas courts did not have general jurisdiction over a Colombian company, Helicol. One of Helicol’s helicopters had been involved in a crash in Peru, and the survivors and representatives of the decedents sued Helicol in state district court in Harris County, Texas. Helicol filed a special appearance and moved to dismiss the case, but the trial court denied the motion. The court of appeals, however, agreed with Helicol that in personam jurisdiction over Helicol was lacking.
Helicopteros Nacionales De Colombia, S.A. v. Hall,
The Supreme Court granted certiorari, and it summarized the pertinent jurisdictional facts:
It is undisputed that Helicol does not have a place of business in Texas and never has been licensed to do business in the State. Basically, Helicol’s contacts with Texas consisted of sending its chief executive officer to Houston for a contract-negotiation session; accepting into its New York bank account checks drawn on a Houston bank; purchasing helicopters, equipment, and training services from Bell Helicopter for substantial sums; and sending personnel to Bell’s facilities in Fort Worth for training.
Helicópteros,
The point at which jurisdictional contacts reach a tipping point, however, has eluded precise formulation. Beyond stating that mere purchases and related travel are not enough, the Supreme Court has given little guidance on the appropriate inquiry for general jurisdiction, although its
Helicópteros
conclusion that general jurisdiction was improper suggests that the requisite level of contacts is fairly substantial. 16 James Wm. Moore et al., Moore’s FedeRal PRACTICE § 108.41 [3] (3d ed.2007); 4 Charles Alan Wright & Arthur R. Miller, Federal Practice & PROCEDURE § 1067.5 (2007) (noting that the Court’s rejection of each contact and its failure to aggregate contacts “suggests very strongly that the threshold contacts required for a constitutional assertion of general jurisdiction over a nonresident defendant are very substantial, indeed”).
Perkins v. Benguet Consolidated Mining Co.,
the only case in which that court has upheld a finding of general jurisdiction, offers an insight into the nature of the contacts required.
Perkins,
A
general jurisdiction inquiry, therefore, is very different from a specific jurisdiction inquiry and involves a “more demanding minimum contacts analysis,”
CSR, Ltd. v. Link,
General jurisdiction has been described as “dispute-blind,” an exercise of the court’s jurisdiction made without regard to the nature of the claim presented. Twitchell, The Myth of General Jurisdiction, 101 Harv. L.Rev. at 613. It involves a court’s ability to exercise jurisdiction over a nonresident defendant based on any claim, including claims unrelated to the defendant’s contacts with the state. 16 Moore’s Federal Practice § 108.40. Some commentators suggest that courts assessing general jurisdiction employ an analyt *169 ical device to determine whether the jurisdiction is, in fact, dispute-blind. Twitchell, The Myth of General Jurisdiction, at 680; Rhodes, Clarifying General Jurisdiction, 84 Seton Hall L.Rev. at 819. They propose that the court construct a hypothetical claim without any forum connection “to insure that any related forum activities of the defendant are not improperly infiltrating the dispute-blind query.” Clarifying General Jurisdiction, 34 Seton Hall L.Rev. at 819. For example:
[A]re the corporate defendant’s actual activities in California so pervasive and extensive that it should be amenable to the adjudicatory jurisdiction of California for a hypothetical employment discrimination claim filed by a New York citizen employed at corporate headquarters in New York? Or, with respect to a foreign corporation, do the corporation’s actual California contacts support jurisdiction even for a hypothetical cause of action arising from its sale of a product in Germany that injured a German citizen?
Id.
at 819-20. Such an inquiry properly frames the issue, as general jurisdiction is based solely on the defendant’s “continuous and systematic” contacts with the forum. Hel

Minden’s Contacts
With this in mind, we turn to an analysis of Minden’s Texas contacts, as the court of appeals concluded that Minden had “continuous and systematic contacts with Texas” sufficient to support general jurisdiction.
We conclude that the relevant period ends at the time suit is filed. As noted above, general jurisdiction is dispute-blind; accordingly, and in contrast to specific jurisdiction, the incident made the basis of the suit should not be the focus in assessing continuous and systematic contacts— contacts on which jurisdiction over any claim may be based.

57 Baylor L.Rev. 135, 238 (2005) (noting that “analyzing the contacts at the time of accrual is not appropriate under the proper explanation of general jurisdiction as dispute-blind general adjudicative authority”);
see also
4 Weight & Miller, Federal Practice & Procedure § 1067.5 (noting that “a court should consider all of a defendant’s contacts with the forum state prior to the filing of the lawsuit”). We also agree that “a mere one-time snapshot of the defendant’s in-state activities” may not be sufficient,
see
Rhodes,
Predictability Principle,
57 Baylor L.Rev. at 239, and contacts should be assessed over a reasonable number of years, up to the date suit is filed,
see Access Telecom, Inc. v. MCI Te-lecomms. Corp.,
We now turn to Minden’s contacts up to the time of suit. A general jurisdiction inquiry can be tedious, as it “demands ... that all contacts be carefully investigated, compiled, sorted, and analyzed for proof of a pattern of continuing and systematic activity.”
Schlobohm v. Schapiro,
1. Texas Trips
The evidence showed that, since 1999, Minden employees attended two Province-sponsored meetings in Dallas. These isolated trips fall short of the “continuous and systematic contact” the Supreme Court requires. In
Helicópteros,
the' Supreme Court rejected the notion that multiple trips to Fort Worth supported general jurisdiction, noting that the trips did not “in any way enhance[ ] the company’s contacts with Texas.”
*171 2. Payments to Texas Vendors
Since October 1, 1999, Minden paid $1,508,467.20 to 136 entities with Texas addresses. The largest payment, $515,650.15, was to Alcon Laboratories in Dallas, Texas, and the second largest, $209,997.36, to Centerpoint Energy in Houston, Texas. Most of the remaining payments are for less than $10,000.00 each. In
Helicópteros,
3. Contracts with Texas Entities
The court of appeals also identified three contracts with a Texas connection: (1) a September 23, 2003 contract with Cox Business Services, a Tyler, Texas-based company, for internet service (at a charge of $59.95 per month) and a cable modem; (2) a July 2002 contract with Lone Star Research, located in The Woodlands, Texas, pursuant to which Lone Star Research would conduct a one-time marketing survey of 200 adult residents in Minden Hospital’s service area; and (3) an April 2001 professional services agreement with Horizon Radiology, P.A., a Texas company, whereby Horizon would provide specialty coverage (via teleradiology equipment) to Minden Hospital, in exchange for $1600 per month.
We agree with the court of appeals that the 2003 Cox contract, entered into after suit was filed, is irrelevant to the jurisdictional inquiry here.
Of the three contracts, the Horizon agreement has the most substantial connection to Texas. The agreement, signed in 2001 and renewed twice thereafter, required that Louisiana-licensed physicians (located in Texas) provide teleradiology services, for which Minden supplied the necessary equipment, in exchange for $1600 per month. Even this agreement, however, does not support general jurisdiction. Hiring a contractor to perform such limited services in the forum state does not equate to “continuous and systematic contacts.”
Even when amassed, Minden’s Texas contacts simply are not “continuous and systematic general business contacts” sufficient to support general jurisdiction, particularly when compared to the substantial, regular business activities conducted by the nonresident defendant in
Perkins. Helicopteros,
*172 B
Jurisdictional Veil-Piercing
As its second basis for general jurisdiction, the court of appeals imputed Province’s Texas contacts to Minden, concluding the two entities operated as a single business enterprise and that Minden, through Province, did business in Texas. In 1925, the Supreme Court of the United States considered whether a North Carolina court had jurisdiction over a nonresident parent corporation whose subsidiary did business in North Carolina.
Cannon Mfg. Co. v. Cudahy Packing Co.,
Through ownership of the entire capital stock and otherwise, the defendant dominates [its subsidiary], immediately and completely; and exerts its control both commercially and financially in substantially the same way, and mainly through the same individuals, as it does over those selling branches or departments of its business not separately incorporated which are established to market the [defendant’s] products in other states. The existence of the [subsidiary] as a distinct corporate entity is, however, in all respects observed. Its books are kept separate. All transactions between the two corporations are represented by appropriate entries in their respective books in the same way as if the two were wholly independent corporations.
Id.
The Court concluded that “the corporate separation, though perhaps merely formal, was real. It was not pure fiction.”
Id.
at 337,
The Court has never disavowed
Cannon,
despite an opportunity to do so. Instead, it essentially echoed the
Cannon
rule in
Keeton v. Hustler Magazine, Inc.,
The Fifth Circuit Court of Appeals followed Cannon in Hargrave v. Fibreboard Corp.:
Cannon ... stands for the proposition that so long as a parent and subsidiary maintain separate and distinct corporate entities, the presence of one in a forum state may not be attributed to the other. Cases in this circuit appear to have followed the Cannon rule in applying the Texas long-arm statute, although sometimes without explicit citation. We have noted often that 100% stock ownership and commonality of officers and directors are not alone sufficient to establish an alter ego relationship between two corporations. Generally, our cases demand proof of control by the parent over the internal business operations and affairs of the subsidiary in order to fuse the two for jurisdictional purposes. The degree of control exercised by the parent must be greater than that normally associated with common owner *173 ship and directorship. All the relevant facts and circumstances surrounding the operations of the parent and subsidiary must be examined to determine whether two separate and distinct corporate entities exist.
Hargrave,
We recently followed
Hargrave
(and, by implication, Cannon) in explaining when the contacts of a related corporate entity may be considered for purposes of determining general jurisdiction.
BMC Software Belg., N.V. v. Marchand,
1. Single Business Enterprise
Here, the court of appeals held that Province and Minden operated as a single business enterprise — a theory we have never endorsed — and, therefore, Province’s Texas contacts could be imputed to Minden.
5
Courts have acknowledged that jurisdictional veil-piercing and substantive veil-piercing involve different elements of proof.
See, e.g., Wells Fargo & Co. v. Wells Fargo Express Co.,
For this reason, fraud — which is vital to piercing the corporate veil under section 21.223 of the Business Organizations Code — has no place in assessing contacts to determine jurisdiction.
See
Tex. Bus. Orgs.Code § 21.223. Similarly, some of the factors courts look to in determining whether an entity may be held liable as a “single business enterprise” are irrelevant to an analysis of jurisdictional contacts. For example, the court of appeals examined whether Province and Minden shared a common name and concluded that “[Min-den’s] partnership name and initials, PHC-Minden, L.P. can be construed as a reference to Province Healthcare Company.”
2. Factors
Instead, we recently outlined the relevant factors for jurisdictional veil-piercing:
To “fuse” the parent company and its subsidiary for jurisdictional purposes, the plaintiffs must prove the parent controls the internal business operations and affairs of the subsidiary. But the degree of control the parent exercises must be greater than that normally associated with common ownership and directorship; the evidence must show that the two entities cease to be separate so that the corporate fiction should be disregarded to prevent fraud or injustice.
BMC Software,
Here, the court of appeals cited the following as evidence that Province and Min-den were a single business enterprise:
the record shows that Province and [Minden] have at least one common employee and that Province pays certain [Minden] employees, although the salaries are intercompany payables. The names of the two companies are similar, and Province employees provide various services to assist [Minden] in its operations. Province exercises control over [Minden]’s revenues and expenditures and oversees [Minden]’s operations, financial performance, and completion of strategic initiatives. Further, Province audits [Mindenj’s financial goals to determine if [Minden] will be able to meet these goals. Considering the totality of *176 this evidence, we conclude that Province and [Minden] have integrated their resources to achieve a common business purpose.
Upon closer examination, however, it is clear that Province does not exercise the sort of control over Minden that is required to fuse them for jurisdictional purposes.
BMC Software,

Conclusion
Minden does not have continuous and systematic contacts with Texas, nor is there any basis for imputing Province’s Texas contacts to Minden. We reverse the court of appeals’ judgment and render judgment dismissing the claims against Minden for want of jurisdiction. Tex R.App. P. 60.2(c).
Notes
. Kimberly-Clark also filed third-party claims against Good Shepherd Medical Center; Longview Emergency Medicine Associates; Schumacher Group of Louisiana; Dr. Russell Riggs; Dr. Rodney Slone; Dr. Don Ferguson; D. Lea, R.N.; C. Bennett, R.N.; and C. Coleman, R.N.
. Charles W. "Rocky" Rhodes and Riata Energy, Inc. submitted amicus curiae briefs.
. The use of the terms "specific” and “general” to connote differing types of personal jurisdiction has been criticized as contributing to the confusion among courts as to the quality and quantity of contacts required for each. See Mary Twitchell, The Myth of General Jurisdiction, 101 Harv. L.Rev. 610, 612-13 (1988) (suggesting that the "general/specific framework” has led to ambiguity and suggesting the terms "dispute-blind” and "dispute-specific” instead). Ironically, Professors von *167 Mehren and Trautman suggested the terms ‘‘specific” and "general” to alleviate the confusion associated with the "in rem,” “quasi in rem,” and "in personam” jurisdictional terminology. von Mehren & Trautman, Jurisdic- how to Adjudicate, 79 Harv. L.Rev. at 1135-36 (noting that "some of the terminology conventionally employed in Anglo-American discussions of jurisdiction to adjudicate is not very helpful”).
. This conflict gives us jurisdiction over this interlocutory appeal. Tex Gov’t Code § 22.225(c).
. The record contains no evidence regarding the structure of Province's ownership of Texas hospitals. That is, there is no evidence regarding whether those hospitals are owned directly by Province or instead by a wholly owned subsidiary like Minden. The parties assume that Province (rather than its subsidiaries) does business in Texas; for purposes of our analysis, we make the same assumption.
