In the billing section of each supplier's account. Most software companies never email the invoice at all; they take the money and file the document behind a login.
Or download Clerk.AI, which signs into them on your Mac and comes back with the documents.
There is a line on the card statement, you know exactly what it is, and there is no email anywhere, which is not you being disorganised, because most of these companies never send one. Below is where 16 of the common suppliers keep theirs, each address opened on 5 September 2026.
If it is a subscription and you cannot find the email, stop searching your inbox. Two more minutes of increasingly creative search terms will not find it either. Go straight to the supplier's billing page, because for this whole category of company that is where the document has been the entire time.
The thing that then costs you a few minutes each is not finding the page. It is remembering which email address you signed up with, whether the account is in your name or the company's, and which of the two Google accounts you are currently signed into. So 16 suppliers is a short list and 16 sign-ins is most of an evening, which is why this is the part of a month that overruns.
Every address below was opened in a browser on 5 September 2026. Each one goes to that supplier's billing area, or to their sign-in page carrying it as the destination. That is what "verified" means here, and it is not a claim about every account type.
The address the invoice is made out to. If the supplier has your name and home address rather than the company's, every invoice from them will have that on it, and it is the kind of detail an accountant queries in month nine rather than month one. Most billing pages have a company-details or tax-details section; filling it in once is the whole fix, and on many of them it is also where you add a VAT number.
The address the invoice is sent to. A billing email that only one person can read is a document nobody else in the company can find. Where a supplier lets you set a separate billing contact, point it somewhere shared.
Open the bank and card statements for the period and go line by line, fetching each document as you reach it. What is left unticked is exactly what you still have to hunt for, and you can see how much is left, and neither of those is true if you start from the receipts you happen to have.
The rest of that method, including the receipts that are in your email and the ones that are still paper, is in how to get your receipts together. What the finished month has to contain is in what your accountant needs from you.
Clerk.AI does this pass on your Mac. It reads the statement, searches your email for the invoices that were emailed, and signs into the billing portals for the ones that were not. All of that happens in a browser on your own machine, with the sessions you already have, and it comes back with the lines it could not settle rather than with all of them.
Whether handing an app your logins is a reasonable thing to do is a fair question, and it has its own page: is it safe to give an app your bank login?
