E-signature send limits and overage fees, compared

Why the advertised price is not the billed price

The price on an e-signature pricing page buys a seat. It does not, on most platforms, buy unlimited sending. The seat comes with an allowance, the allowance is usually annual, and the cost of exceeding it usually lives on a different page — a support article, a help-centre entry, or a sales conversation.

None of that is hidden exactly. It is just kept somewhere other than where the decision gets made, and the allowances are quoted in a unit ("per user per year") that is hard to compare against a monthly workload. This article puts the numbers in one place, with the vendor's own page cited for each.

Every figure below was read from the vendor's own documentation on 2 September 2026. Where a vendor does not publish a number, that is stated rather than estimated.

What each platform allows

| Platform | Plan | Included | Unit | |---|---|---|---| | DocuSign | eSignature Standard / Business Pro (annual) | 100 envelopes | per user, per year | | DocuSign | eSignature Standard / Business Pro (monthly) | 10 envelopes | per user, per month | | DocuSign | eSignature Personal | 5 envelopes | per month | | SignNow | Business, Business Premium, Enterprise | 100 signature invites | per user, per year | | Adobe Acrobat Sign | Sign SMB, for Business, for Enterprise | 150 transactions | per user licence, per year | | Adobe Acrobat Sign | Acrobat Standard / Acrobat Pro | Unlimited | — | | PandaDoc | Free | 60 documents | per year | | PandaDoc | Starter, Business, Enterprise | unlimited sent by hand; 10/month or 120/year of automated generation, first 12 months only | per account | | PearSign | Free | 10 envelopes | per month | | PearSign | Professional | 1,000 envelopes | per month, whole account |

Two things to notice before the prices. First, most of these are annual allowances on a monthly bill, so there is no monthly reset to rescue you — a busy first quarter spends the year. Second, they are per user, which means the allowance grows only by buying another seat, and buying a seat to unlock sending capacity is the mechanism by which per-seat pricing becomes volume pricing.

What going over costs

DocuSign publishes a full table. Excess envelopes on Standard and Business Pro are billed "Pay-As-You-Go" per envelope, and buying capacity in advance ("Subscribe and Save") is cheaper:

| DocuSign plan | Bought ahead | Pay-As-You-Go | |---|---|---| | Standard Annual | $3.00 | $3.60 | | Standard Monthly | $4.50 | $5.40 | | Business Pro Annual | $4.80 | $5.80 | | Business Pro Monthly | $6.50 | $7.80 |

Personal plans are excluded from Pay-As-You-Go, so a Personal account that reaches its limit stops sending rather than overspending.

SignNow charges per additional invite, and the rate depends on tier — it is not a single flat rate, despite several comparison articles quoting one:

| SignNow plan | Per additional invite | |---|---| | Business | $0.96 | | Business Premium | $1.80 | | Enterprise | $3.60 |

PandaDoc splits its metering in two, and only half of it is on the pricing page. Manually sent documents are unlimited on paid plans; automated generation — Forms, Bulk Send, Automations, Zapier/Make/Workato — is metered as usage credits, 10 a month or 120 a year on Business and Enterprise and only for the account's first 12 months. After that renewal the included figure is zero. The pricing page's own FAQ separately prices excess documents at $3.50 on Starter Monthly, $2.00 on Starter Annual and $2.60 on Business Monthly, and the credit overage rate is not published at all — it is "the applicable per unit fee on the Customers then current Order." Nothing rolls over.

Adobe publishes no overage price at all. The transaction-limits page directs customers who need more than 150 per user to speak to a sales agent about buying a volume of transactions or a site licence. The cost of exceeding the allowance therefore cannot be worked out before you buy.

The same workload, costed

Take five people sending 300 documents a month — 3,600 a year. That is an ordinary volume for a small sales or operations team, and it is enough to clear every allowance above. Overage only; the subscription is on top of these figures.

| Platform and plan | Included / yr | Over | Rate | Overage / yr | |---|---:|---:|---:|---:| | PearSign Professional | 12,000 | 0 | — | $0 | | SignNow Business | 500 | 3,100 | $0.96 | $2,976 | | SignNow Business Premium | 500 | 3,100 | $1.80 | $5,580 | | SignNow Enterprise | 500 | 3,100 | $3.60 | $11,160 | | DocuSign Standard Annual | 500 | 3,100 | $3.60 | $11,160 | | DocuSign Standard Monthly | 600 | 3,000 | $5.40 | $16,200 | | DocuSign Business Pro Annual | 500 | 3,100 | $5.80 | $17,980 | | DocuSign Business Pro Monthly | 600 | 3,000 | $7.80 | $23,400 | | Adobe Acrobat Sign for Business | 750 | 2,850 | not published | not derivable | | PandaDoc Free | 60 | 3,540 | must upgrade | — | | PandaDoc Business, automated, yr 1 | 120 | 3,480 | not published | not derivable | | PandaDoc Business, automated, yr 2+ | 0 | 3,600 | not published | not derivable |

The arithmetic is deliberately plain so it can be checked: included is the per-user allowance times five, over is 3,600 minus that, and the last column is the two multiplied. PearSign Professional is $39 a month — $468 a year — for an account-wide 1,000 envelopes a month, so 3,600 a year sits inside the plan and the overage column is zero rather than small.

The point of the table is not that one number is bigger. It is that on most of these platforms the overage is larger than the subscription at a volume the subscription is nominally sold for, and that this only becomes visible after you have committed.

The counting rules matter as much as the caps

An allowance is only as generous as what it counts against. Three rules recur, and each one surprises somebody:

A send counts when it leaves, not when it completes. DocuSign states that an envelope counts once sent "whether or not the Envelope is signed or completed." A contract nobody ever signs still spends your allowance. Drafts do not count, and on DocuSign, correcting an envelope already in flight does not count again.

Bulk sends count per recipient. DocuSign counts each row of a bulk recipient CSV as a separate envelope — a 100-row file creates 99 envelopes, the header excluded. On a 100-envelopes-per-user-per-year allowance, one bulk send can spend an entire seat's year.

Reusable links can count per use. A DocuSign PowerForm that skips the signer information form and goes straight to the document counts an envelope each time the link is used. A public link on a website therefore has an open-ended cost, which is the opposite of how a public link feels.

Adobe adds a fourth category: per-transaction ceilings independent of volume. 10 MB per uploaded file, 100 pages per transaction (500 on Enterprise), 10 signers on Acrobat Standard or 25 elsewhere, and knowledge-based or phone authentication capped at 50 a year — zero on Acrobat Standard and Pro. Acrobat Sign also throttles requests per minute, hour and day by user, IP or agreement.

"Unlimited" is also bounded

DocuSign's higher Intelligent Agreement Management tiers are sold with unlimited envelopes, and Acrobat Standard and Pro are listed as unlimited transactions. Both are still bounded in practice. DocuSign's envelope-allowance FAQ states that send volume is subject to a Reasonable Use Policy and that it "may prevent you from sending new envelopes if your send volume exceeds Reasonable Use."

That is a reasonable thing for a platform to reserve, and worth knowing before you architect a workflow on the assumption of no ceiling. Unlimited means no metered charge, not no limit.

How to check your own numbers

Whatever you are choosing between, three questions settle it faster than a feature matrix:

1. What is the allowance, and in what unit? Convert everything to per year per account, not per user per month. Five seats at 100 a year is 500 a year, not "100".
2. What is the price of the 501st? If it is not on the pricing page, find the support article. If there is no support article, that is the answer to a different question.
3. What counts? Ask specifically about unsigned sends, bulk sends and reusable links. Those three are where the gap between expected and billed volume comes from.

PearSign states its allowance on the pricing page and prices the plan by account rather than by seat: 10 envelopes a month free with no card, 250 a month on Starter at $15, 1,000 a month on Professional at $39, 4,000 on Business at $129. Team members are included in the plan rather than multiplying it.

FAQ

Which e-signature platform has no envelope limit?

Plans sold as "unlimited" exist — DocuSign's Intelligent Agreement Management tiers, and Adobe Acrobat Standard and Pro for e-signing — but both remain subject to fair-use provisions, and DocuSign states explicitly that it may prevent further sending if volume exceeds Reasonable Use. A more useful question than "is it unlimited" is "what is the allowance and what does the next one cost", because a stated allowance with a stated overage price is predictable, while an unstated ceiling is not.

Does an unsigned document still count against my limit?

On DocuSign, yes. Its documentation states an envelope counts toward the allowance once sent, whether or not it is signed or completed. Envelopes still in Drafts have not been sent and do not count, and documents you sign yourself through Sign a Document do not count. Most platforms count on send for the same reason: sending is the billable event.

How much does DocuSign charge for extra envelopes?

Between $3.00 and $7.80 per envelope, depending on plan and billing cycle. Buying capacity in advance is cheaper than Pay-As-You-Go: Standard Annual is $3.00 bought ahead against $3.60 as it happens, and Business Pro Monthly is $6.50 against $7.80. Personal plans cannot pay as they go.

Does SignNow really charge $1.50 per extra invite?

No. That figure circulates widely in comparison articles, but SignNow's own help centre lists three different rates by tier: $0.96 on Business, $1.80 on Business Premium and $3.60 on Enterprise. The underlying cap is real — 100 signature invites per user per year, with no rollover — but the single flat rate is not.

What is PandaDoc's document limit on paid plans?

It depends how the document is sent, and the pricing page only tells you half of it. Sent by a person: unlimited on Starter and above. Generated by a workflow: metered as usage credits — 10 a month or 120 a year on Business and Enterprise, and only for the first 12 months of the account's life, after which no free credits are included. The Free eSign plan is 5 uploaded documents a calendar month to a maximum of 2 recipients each. The credit figures are in the help centre's Account Billing and Ownership article rather than on the pricing page. See PandaDoc's document limit and per-document fees.

Do unused envelopes roll over to next year?

Generally not. SignNow states that unused invites do not roll over and that every subscriber starts each year with a fresh quota. PandaDoc states that unused documents do not roll over between billing periods. This is what makes annual allowances harder to manage than they look: an underused first half does not fund a busy second half.
