When a vendor won't accept digital checks

You've moved your vendor payments onto one system. Checks go out digitally, the vendor pulls the check from a portal and deposits it the same day, and your accounts payable finally runs without a checkbook and a stack of envelopes. Then one vendor's accounts-receivable team calls your buyer and says they don't accept a digital check platform. They take ACH, cash, or a paper check in the mail — and that's the list.

This is common, and it is almost always one specific vendor: a large, established distributor whose AR department was built long before digital instruments and hasn't changed its intake rules. You are not going to win that argument, and you don't need to. You also should not tear up how you pay everyone else to accommodate one supplier's policy. What you want is narrow: switch that one vendor to mailed paper checks, and leave every other vendor on the instant digital delivery that's already working.

In ShelfSpace, that's a per-vendor setting. It takes under a minute, it lives on that one vendor's record, and it touches nothing else. Here's how it works and what actually happens after you flip it.

One vendor, not your whole list

The instinct when a vendor refuses digital is to worry the whole operation has to change. It doesn't. Every vendor in ShelfSpace has its own Default Payment Method — how you pay that vendor by default, independent of every other vendor. Setting one vendor to paper is exactly like giving one vendor different payment terms: it's scoped to them.

So the distributor that only takes paper gets mailed checks. Your other vendors keep getting a Check 21 digital check they download and deposit the same day. Nobody else notices, because for everybody else nothing changed.

How to switch a vendor to mailed checks

The whole change is four steps inside the vendor's settings. You'll need a complete US mailing address for the vendor — if you don't have one yet, the platform asks for it as part of the switch.

The Default Payment Method card is the same one that governs every payment channel. It sets how you pay that vendor by default; every Pay screen preselects it, and you can still switch the channel on any single payment. Four options sit in the card:

• ACH bank transfer — the platform sends funds directly to the vendor's linked bank account, so no check is generated.
• Digital check (the default) — the platform generates a check the vendor downloads from the portal.
• Physical (mailed) check — the platform prints on bank-grade check stock and mails it by USPS, and a printed copy is saved to the portal.
• Manual payment — you pay the vendor directly with your own check, cash, or wire; the platform records the payment but generates no check.

What actually happens after you switch

When you pick Physical (mailed) check, the platform confirms the switch in plain terms before it commits: future checks for that vendor will be printed on bank-grade stock and mailed by USPS. A non-negotiable copy will be saved to the portal so the vendor can see the check details, but only the mailed paper check is cashable — and it typically takes 3–5 business days for the vendor to receive.

From that point on, the platform defaults to mailing paper checks to that vendor. Every future check — an AP invoice payment or a consignment settlement — prints and mails without any extra steps from you. There's no separate "mail this one" action to remember; paper is simply the default for that vendor now. If you ever need a one-time exception, override the channel on that single payment; to go back permanently, reopen the card and pick Digital check or ACH.

A mailing address is required — and the fallback keeps it safe

A mailed check can only go where there's an address, so the platform won't mail into the void. If the vendor's profile is missing any part of a complete address — or the account isn't provisioned for mail yet — the platform falls back to a digital portal check instead of holding the payment. The vendor still gets paid; the check just lands in the portal the way it always has until the address is complete.

That fallback is what makes the switch safe to flip. The worst case isn't a missed payment — it's a check that arrives digitally, which is exactly where you started. Add the mailing address and paper takes over on the next check. Keeping that address current is the one piece you own; the printing, addressing, USPS handoff, and tracking are the platform's job.

The honest tradeoff: paper is slower

Be straight with the vendor about what changes. A mailed check gives the same paper-check paper trail as a digital one — same instrument, same traceability, same bank-grade stock. What you trade is speed. A digital portal check is available to deposit the same day it's cut; a mailed check has to travel, and USPS typically takes 3–5 business days to deliver it.

The $5 per mailed check covers printing on bank-grade stock and USPS postage. It's the one payment channel with a per-check cost — ACH transfers and digital portal checks are included in your plan. For most operators, paying $5 to keep one stubborn distributor happy is a rounding error against the cost of falling back to writing that vendor a check by hand every week. The full mechanics live in the mailing checks guide, and the pricing is on the pricing page.

When ACH is the better answer

Mailing isn't the only way to satisfy a vendor who rejects a digital check. That same AR team usually named three things it accepts — ACH, cash, or paper — and ACH may be the cleaner fit. If the vendor will link a bank account, an ACH bank transfer sends the money straight into their account with nothing to print, mail, or deposit, and no per-check cost. It's also faster than paper.

Use paper when the vendor specifically wants a physical instrument, or won't share bank details. Use ACH when they'll take direct deposit and just don't want a "digital check." Both are per-vendor settings in the same Default Payment Method card, so you can offer the vendor whichever one their AR team prefers and change your mind later without disrupting anyone else.

The point of all of it is the same: one vendor's payment quirk shouldn't force a change on the rest of your payables. It doesn't. You switch the one vendor, everyone else stays on the fast path, and the paper trail stays intact either way. Cannabis payment rails already break often enough on their own — see what happens when your bank drops you — so the flexibility to pay each vendor the way they'll actually accept is worth having built in.

A vendor refusing digital checks isn't a reason to change how you pay everyone. It's a one-vendor setting — switch that one to paper or ACH, and leave the rest on the fast path.
