Contract and invoice automation runs the paperwork chain after a deal closes: it generates the contract from your CRM, sends it for signature, raises the invoice, sends it, and chases payment, updating the CRM and accounting system as it goes. Anything non-standard, a custom clause or a partial payment, stops for a person. Most teams are live in two to three weeks.
The problem
The work after a deal closes is a relay race across systems that do not talk to each other. The deal lives in your CRM, the contract gets built in a doc tool, the invoice comes out of your accounting software, and the chasing happens from someone's inbox. So a closed deal kicks off a familiar chain done by hand: copy the terms into a contract, send it for signature, wait, nudge, build the invoice off the same details, send it, then follow up when it goes unpaid, and update two systems at every step so the CRM and the books agree. It is low-skill, high-stakes work, and it always sits behind whatever is louder that week.
Put a number on it. Allianz Trade's 2024 DSO and Working Capital report found that global days sales outstanding, the average gap between making a sale and collecting the cash, rose three days in 2023 to reach 59 days. That is the largest jump since 2008, across a survey of about 45,000 listed companies. For a 40-person B2B firm invoicing around $200,000 a month, 59 days is close to $390,000 of already-sold work sitting uncollected at any one time. ($200,000 a month at 59 days is roughly $390,000; the 59-day figure is Allianz Trade's, the cash figure is that rate scaled to one firm's billings.)
The hours are not even the real cost. The real cost is the invoice that goes out four days late because it waited behind everything else, the client who was never chased because the follow-up lived in someone's head, the deal that stalls at signature because nobody sent the reminder, and the month-end where the CRM and the accounting system disagree and somebody reconciles them by hand. Cash comes in slower than it should, and none of it shows up as a line item.
How the automation works
A deal is marked closed in the CRM.
That is the trigger. The automation generates the contract from that deal record, fills in the terms and client details, and sends it out for signature.
The signed contract raises the invoice.
Once the signature comes back, it builds the invoice from the same deal data, sends it to the client, and follows up on a set schedule if it goes unpaid, so nobody has to remember to chase.
It keeps the CRM and accounting system in step.
At each milestone, signed, invoiced, paid, it updates the CRM stage and posts the status to the accounting system, so both always show the same true state instead of drifting apart.
The pieces are proven: contract generation from templates, e-signature, invoicing, payment reminders, and connectors into the CRM and accounting system. The real work is the wiring. Most deals are standard, but the ones that are not are exactly where this has to be careful: a clause negotiated over email, a discount that never made it into the CRM, a client who pays half up front and half on delivery. Sending a wrong invoice or a bad contract automatically is worse than a manual slip, because it goes out fast under your name and you have to walk it back with a client. So the system is built to send only the clean, standard cases on its own and hold anything unusual for a person to approve. Keeping the CRM and the books showing the same truth as money moves is the other hard part. That is what gets set up, tested, and handed over during implementation.
What this looks like in practice
Deals in Attio, contracts through DocuSign, books in QuickBooks, one operations coordinator handling the post-sale admin.
- Every closed deal starts a manual chain: copy the terms into a contract, send for signature, chase it, build the invoice, send that, chase again.
- It takes 3 to 4 days on average from a deal closing to the invoice actually going out, because it waits behind everything else on the coordinator's plate.
- The CRM says one thing and QuickBooks says another, so the two get reconciled by hand at month-end.
- The contract goes out for signature within minutes of a deal closing, and the invoice follows the moment it is signed.
- Time from closed deal to invoice sent drops from 3 to 4 days to same-day for standard deals; only the custom ones wait on a person.
- Attio and QuickBooks stay in sync automatically, so the month-end reconciliation of the two is mostly gone.

Who this fits
- Enough deals closing that the post-sale paperwork is a real recurring job, not a once-in-a-while task
- 10 or more employees, with someone who owns contracts, invoicing, or both
- Deals live in a CRM while the contract tool and accounting system sit apart, so the same details get retyped between them by hand
- You want a person to approve anything non-standard, a custom clause or a partial payment, rather than let everything send on its own
