The real options on the table before we picked this stack for Billed.
| Alternative | Best For | Cost Signal | Biggest Gotcha |
|---|---|---|---|
| QuickBooks Online or Xero | Accountant-owned finance with strong bank feeds | $25-$235/mo per company | Overkill for solo freelancers and micro-businesses; the learning curve is the primary churn reason. |
| Wave or Zoho Invoice | Basic invoicing for sole proprietors | Free to $29/mo | Expense capture and estimate-to-invoice flows are limited; multi-currency breaks at scale. |
| Custom invoicing on WordPress + plugins | Agencies running their own client portal | $2k-$8k build + $60/mo hosting | PCI compliance and recurring-billing logic get hairy fast; plugin stack breaks under update pressure. |
| Custom Laravel invoicing SaaS (our build) | Small businesses needing integrated estimates, expenses, and recurring invoices | ~$85k-$130k build + $800/mo ops and payments | PCI scope (even with Stripe) forces additional hardening; adding a new tax jurisdiction takes 2-4 days of engineering. |
Specific numbers — build cost, ops, and the scale at which custom beat the off-the-shelf alternative.
Billed cost ~$110k to build + ~$900/mo ops including Stripe fees on a revenue-share model. QuickBooks licences for the target segment (1-5 seat micro-businesses) averaged ~$45/seat/mo; against a 5k-user subscriber base at $12/mo ARPU Billed broke even at month 24 net of Stripe fees and support cost. Below 1,200 active paid users reselling QuickBooks is more profitable; above 8k active users Billed nets roughly $180k/yr in gross margin and the brand moat starts compounding through integrations QuickBooks will not prioritise for micro-SMBs.
Specific production issues this pattern has surfaced for real teams.
Invoices issued in one currency and paid in another capture rates at different timestamps; without a defined rate policy, reconciliation reports showed phantom P&L swings of 1-2%.
Gmail and Outlook occasionally flag invoice attachments as spam; adding SPF/DKIM/DMARC on the sending domain plus a PDF link fallback cut delivery failure reports by over half.
When clients paid less than the invoice total, the default full-payment assumption mis-tagged invoices as closed; a partial-payment ledger state was backported after early SMB support tickets surfaced the issue.
