Quick answer · the 30-second read
In the US, most leading systems include e-signature rather than integrating with an outside platform. MyCase and PracticePanther build their own. Filevine supplies its own, called Vinesign. Clio includes Dropbox Sign. Smokeball is the main exception, routing signing through InfoTrack, which offers DocuSign. So for most US firms the practical question is whether the signing already included in your case management subscription is good enough. Often it is.
What each practice management system offers
For a law firm, this question usually decides the purchase. Signing that does not connect to the case management system means documents moving by hand between two places, which is where errors and lost time come from. The table covers five systems used widely by US firms and records what each provider publishes about its own product.
Practice management system | Signing option | How it works |
MyCase | Its own, included | MyCase states that e-signature is built directly into the product, with unlimited e-signature included on its Pro and Advanced plans. Signed documents save back to the file automatically. Check which plan you are on, as inclusion is not universal across tiers. |
PracticePanther | Its own, included | PracticePanther describes e-signature as one of its in-house tools, not requiring an additional subscription or third-party product. |
Filevine | Vinesign, its own product | Vinesign is built by Filevine and works inside it, filling in contact details from the file and saving signed documents back automatically. It is also sold separately, so it is priced as its own product rather than simply bundled. |
Clio | Dropbox Sign, DocuSign | Dropbox Sign is built into Clio Manage and Clio states it is included in a Clio subscription at no additional cost. A DocuSign integration is listed separately in Clio’s app directory. Clio’s pages disagree about availability outside the US, which matters more for UK firms than US ones. |
Smokeball | DocuSign or InfoSign, through InfoTrack | Smokeball’s support documentation states the InfoTrack integration must be enabled for signing to work at all. Within that, you choose DocuSign or InfoTrack’s own InfoSign. Signing supports multiple signers and witnesses. |

Why do US systems build their own signing?
Because e-signature has become a standard expectation rather than a specialist product. Sending a retainer for signature is such a routine part of running a US firm that the case management providers have absorbed it, in the same way they absorbed billing and client portals.
Including signing removes a reason for a firm to buy anything outside the platform, and it makes the subscription look better value against competitors. MyCase lists unlimited e-signature on its Pro and Advanced plans, which is a direct answer to firms comparing against a per-envelope subscription elsewhere.
Filevine took a different route and built Vinesign as a product in its own right, sold separately as well as used inside Filevine. That means it is priced as a product rather than absorbed into the case management fee.
How does this differ from the UK?
Considerably, and it is worth knowing if your firm works across both. In the UK, the leading systems integrate with DocuSign rather than building their own, and firms usually buy that subscription separately. In the US, most leading systems include signing, so a US firm often pays nothing extra. A UK firm usually pays twice. See Which e-signature platforms integrate with UK legal practice management software?.
One company appears in both markets. InfoTrack sits behind signing for Smokeball in the US and for LEAP in the UK, in each case supplying DocuSign underneath rather than a direct connection between the case management system and DocuSign.
When is the included option not enough?
Three situations come up most often.
Identity verification. If your work requires knowledge-based authentication, where the signer answers questions drawn from public records, check whether the included tool offers it. It is widely used in higher-risk transactions, such as remote real estate signings and financial agreements.
Qualified electronic signatures, the highest tier under European rules. A US firm acting for European counterparties may need them, and no case management system’s included signing offers them. See Which e-signature platforms include qualified electronic signatures, and at what tier?.
Signing outside the case management system. If your firm signs documents that never become part of a client file, such as vendor contracts or employment paperwork, an included tool tied to files may be awkward to use.
What to ask before you buy
- Ask whether signing is included in the subscription or charged separately, and whether there is any cap on volume.
- Ask whether the signed document and its audit trail save back into the file automatically.
- Ask what identity checks are available, and what they cost.
- Ask whether the included signing can be used for documents that are not attached to a client file.
- Ask what happens to documents in progress if you leave the platform.
Our verdict
Try what you already have before buying anything. If your firm runs MyCase, PracticePanther or Clio, signing is already included in what you pay. A separate subscription only makes sense if the included tool cannot do something you need. The reasons to pay for something separate are specific. Identity checks such as knowledge-based authentication, signing that has to happen outside the case management system, or work that needs qualified electronic signatures for European counterparties. If none of those apply, the included option is usually enough. On Smokeball, budget for InfoTrack. Signing does not work without it, so it is a second supplier relationship rather than a feature of the software you have bought. Do not assume your existing platform will connect.
