Revenue Backlog

Revenue backlog is the money your agency is contractually committed to earn but hasn't earned yet. It's the total value of signed contracts and retainers minus the revenue you've already recognized. If you have $500,000 in signed project contracts and you've completed $200,000 worth of work so far, your revenue backlog is $300,000.

For retainer-based agencies, backlog includes the remaining value of multi-month or annual retainer agreements. If a client signed a 12-month retainer at $10,000/month and you're in month 4, the backlog on that contract is $80,000 (8 remaining months). Add up all your contracts and you get your total backlog — the revenue that's essentially "in the bag" for the coming months.

Revenue backlog is one of the most important metrics for agency stability and valuation. It's forward-looking in a way that current revenue isn't. A $3M agency with $2M in backlog has a very different risk profile than a $3M agency with $300K in backlog. The first agency has clear visibility into the next several months of revenue. The second is dependent on winning new work almost immediately to maintain their run rate.

Backlog is your agency's financial safety net. It tells you how long you can sustain current operations if you stopped winning new business today. A healthy agency typically has 3-6 months of backlog, meaning they could maintain revenue for 3-6 months purely from existing contracts.

It's also the number that investors, acquirers, and banks look at when evaluating agency health. Strong backlog makes it easier to secure lines of credit, negotiate better lease terms, and command a higher valuation multiple. It de-risks the business and demonstrates that your client relationships are durable, not transactional.
