Bank accounts, payment processors, invoicing and reconciliation. Unglamorous, and it decides whether you can actually collect money.
12 min read · Level 2
How you collect money matters as much as how much you collect — the same annual contract paid by card upfront or invoiced at sixty days produces identical revenue and completely different companies. Founders treat payment terms as administration rather than as a lever, and then raise equity to solve a timing problem that a discount for upfront payment would have fixed.
The practical money infrastructure:
A business bank account, separate from personal — non-negotiable once incorporated A payment processor to take card payments Invoicing for anything not paid by card Expense management so spending is visible Reconciliation — matching what the bank shows against what your records say
Because mixing personal and business money makes bookkeeping painful, tax filings unreliable and due diligence unpleasant — and in some structures it can undermine the liability protection incorporation was meant to give you.
And because how you collect money directly affects cash flow. Card payment on signup arrives today. A 60-day invoice arrives in two months.
The stack a small software company actually needs:
The cash-flow difference is the point. Same $12,000 annual contract:
All three are the same revenue and three completely different cash positions. Offering a discount for annual upfront payment is often the cheapest financing a startup can get.
First-time founders often run business expenses through a personal account for months, then spend days reconstructing it at year end. Separate accounts from the day you incorporate.
The second mistake: only offering invoicing because processor fees feel expensive. The fee is usually far cheaper than the cash-flow cost of waiting 60 days.
The third: not reconciling. If your records and your bank do not match, one of them is wrong, and unreconciled books make every downstream number unreliable.
Same week. Never mix personal and business money.
Fees are real and instant payment is usually worth more than the fee, especially early.
10–20% off for paying a year ahead is often the cheapest financing available to you.
Automatic categorisation removes most bookkeeping effort and keeps records current.
Spending is visible in real time, and nobody is out of pocket.
Thirty minutes. Mismatches are either errors or something worse, and both want finding early.
From incorporation, and reviewed whenever you move upmarket to customers with longer payment cycles.
Do not over-engineer this pre-revenue. One account, one processor and accounting software is the whole stack until you have a team.
Founders resist card fees of two to three percent and then accept sixty-day invoicing without comment. The fee is a known small cost; the wait is two months of working capital tied up and a meaningful risk of never collecting at all.
Compare the fee against the cash-flow cost of waiting, not against zero. Instant payment is usually worth well more than the percentage.
Six months of business spending through a personal account is genuinely miserable to reconstruct, produces books nobody trusts, and in some structures weakens the liability separation that incorporating was meant to provide.
Separate accounts the week you incorporate. The cost of not doing it is entirely paid later, at a worse exchange rate.
