Founder Playbook: How to Get Customers to Pay on Time

Startup founders obsess over ARR and churn. Almost none of them have a collections process.

Then they wonder why cash is tight despite "strong revenue."

It’s not just that founders ignore collections. At most early-stage companies I meet, no one is responsible for collections. Not one person. Invoices go out, and then everyone just hopes for the best.

Here's what actually works:

1. Invoice before the renewal date, not when you get around to it. Sounds obvious. Most early-stage companies batch invoices at the end of the month, or worse, forget entirely. Set up automated billing on the contract start date. Every day of delay is a day you're financing your customer for free.

2. Make payment frictionless. If your customer has to cut a paper check or wire money manually, you've already lost days. Offer ACH, credit card, and auto-pay from day one. The easier you make it, the faster you get paid.

3. Build a simple follow-up sequence:

• 7 days before due: friendly reminder

• Day of: resend invoice + payment link

• 3 days late: direct email from finance or CS

• 10 days late: phone call, include both finance and CS

• 30 days late: formal notice, turn off product access

4. Send the invoice to the right person. In B2B SaaS, the person who signs the contract is rarely the person who approves payment. Make sure you have the right AP contact, email, and invoices requirements at the time you sign the contract. Otherwise, you will waste time gathering information before you are able to send the first invoice.

5. Push payment terms as much as you can. Net 30 is not a law. Net 15 is reasonable for most companies. Smaller customers may even accept net 0 (due on receipt). Whatever you agree to, make sure it makes it into the contract.

6. Be willing to turn off service and follow through. This one makes founders uncomfortable. But here's the truth: the finance teams at your customers know exactly which vendors will tolerate late payment and which ones won't. If you always let it slide, you've trained them to deprioritize you. Turning off access for a significantly overdue account sends an unambiguous signal. And it works. Most customers will pay within hours. Put the policy in your contract, communicate it clearly, and enforce it consistently.

7. Review AR weekly. If you only review AR monthly, then it’s impossible to execute a high resolution follow-up sequence. A 10-minute AR aging review every week along with a follow-up sequence prevents most issues.

We enforce these policies with the companies we work with and have seen cash flow improve dramatically.

For high-growth companies, pulling collections forward by 30 days can easily add 3-6 months of runway.

There are not many ways to improve runway to that degree without giving up equity, adding debt, or cutting costs.

All it takes is a little bit of consistency and process.
