OTHER
Owner Draw / Distribution (money you take out for yourself)
Owner Contribution (money you put in from personal funds)Weekly (pick a day, be consistent):
- [ ] Categorize new transactions in accounting software
- [ ] Upload receipts for any expense over $75
- [ ] Reconcile bank account (does your software match your bank?)
- [ ] Note any unusual transactions to ask your accountant about
Monthly (first week of each month):
- [ ] Review Profit & Loss statement
- [ ] Check: Is revenue matching what Stripe shows?
- [ ] Check: Are expenses categorized correctly?
- [ ] Review cash balance — how many months of runway do you have?
- [ ] Set aside estimated tax payment (see Tax section)Example:
- Customer pays $1,200 for annual plan on March 1
- You DON'T book $1,200 as March revenue
- You book $100/month for 12 months (March through February)
Why: You owe them 12 months of service. Until delivered, it's "deferred revenue" (a liability).Due dates:
- Q1: April 15
- Q2: June 15
- Q3: September 15
- Q4: January 15 (of the following year)
How much to set aside:
- Rule of thumb: 25-30% of net profit (revenue - expenses)
- Transfer this to a separate savings account each month
- Pay quarterly estimates from that accountLikely deductible (confirm with your accountant):
- [ ] Hosting and infrastructure costs
- [ ] Software subscriptions used for business
- [ ] Payment processing fees (Stripe)
- [ ] Contractor payments
- [ ] Home office (dedicated space, % of rent/mortgage)
- [ ] Internet (business % of your bill)
- [ ] Computer and equipment
- [ ] Domain registration and renewal
- [ ] Professional services (legal, accounting)
- [ ] Business insurance
- [ ] Education directly related to your business
- [ ] Marketing and advertising expenses
- [ ] Travel for business purposes (conferences, customer meetings)Do it yourself: Pre-revenue to ~$2k MRR (use software, keep clean books)
Annual tax prep: $2k-10k MRR (hire a CPA for year-end, do bookkeeping yourself)
Monthly accountant: $10k+ MRR (hire a bookkeeper or service like Bench)Review monthly. Ask:
- Is revenue growing month over month?
- Are expenses growing faster than revenue?
- What are my top 3 expense categories?
- What's my profit margin? (profit / revenue × 100)Review monthly. Ask:
- How much cash do I have today?
- How many months of expenses can I cover? (runway)
- Am I cash-flow positive? (more coming in than going out)Review quarterly. Less important at early stage, but needed for:
- Applying for business loans or credit
- Talking to potential investors
- Understanding deferred revenue| Mistake | Fix |
|---|---|
| Mixing personal and business finances | Separate bank accounts from day one |
| Not tracking expenses | Categorize weekly. 30 minutes prevents 30 hours of cleanup |
| Ignoring estimated tax payments | Set aside 25-30% of profit monthly in a separate account |
| No receipts for expenses | Save digital copies of everything over $75 |
| Doing books once a year | Weekly categorization, monthly review |
| DIY taxes past $10k MRR | Hire a CPA. They pay for themselves in avoided mistakes |
| Confusing Stripe revenue with accounting revenue | Stripe payouts include refunds, fees, and timing differences |
| No emergency fund for the business | Keep 2-3 months of expenses in the business account |
