Each fall, ServiceCrowd works with agency owners to build next year's plan: an operating model with a revenue target, a budget and a hiring plan and investment plan. While the operating plan is important for anticipating timing around investments and hiring, it also serves a couple of other purposes.

An agency’s financial operating model is only as accurate as the data your processes capture. Below are five metrics that greatly improve forecasting and planning accuracy; each relies on a sound operating process to be accurate. If you can’t rely on these metrics today, part of your annual plan should be to change that.

# Cost of Services as a Percentage of Revenue, by Service Line

What it is. Your cost to deliver each service (your team's time, contractors, anything else tied directly to delivery), expressed as a percentage of the revenue that [service line¹](https://servicecrowd.io/insights/five-numbers-agency-owners-need-for-accurate-annual-planning?hs_amp=true#foot-note-1) brings in. 

Some people call this *COGS (Cost of Goods Sold)*. As agency operators, we prefer *COS (Cost of Services)*. Either way, the important part is by service line, not one blended number for the whole agency.

Why it matters for planning. COS as a percentage of revenue lets you forecast costs as revenue scales based on where the revenue is coming from, not just on top-line revenue. That matters a lot when growth isn't even. Say Service Line A work costs 55% of revenue to deliver and Service Line B has a COS of 40%, and you're planning for most of next year's growth to come from Service Line A. If you forecast costs off a blended rate somewhere in the middle, you'll understate what that growth costs to service, and you won't find out until gross margin comes in lower than planned.

What has to be in place to have it. Two things.

First, accrual-based accounting that recognizes revenue by service line in the period the work was delivered, so revenue in a given month aligns with the costs from that same month. On cash-basis books, the two drift apart. Bill a $60K project upfront in March, deliver it April through June, and March looks great while April through June look like you're paying people to sit around. Neither month tells you what that work cost to deliver.

Second, actual costs need to be allocated to specific projects for each service line. In practice, that usually means people tracking time against projects, contractors invoicing against projects, and every project tagged to the service line it belongs to. Without that, you can see what the agency spent, but not what each service costs. New achievement!(*read in the Dungeon Crawler Carl AI voice*). You’ve now unlocked project profitability, which can help you further analyze costs, exclude COS outliers from your forecast, and say no to shit work that isn’t bringing in any margin.

# New business win rate

What it is. The share of your recent new-business opportunities that turned into closed-won deals. The recent part matters. You want the rate you're winning at with what you charge today, not what you were winning two years and two price increases ago.

Why it matters for planning. It helps inform how many of next year's opportunities you can realistically expect to convert into new business. It gives you a new business number grounded in your actual track record instead of a target you typed in because it felt right. And if you're planning to change pricing next year, that's worth flagging up front, because the win rate you've earned at today's prices may not hold.  
Win rate is only half of the equation, though. The other half is how many opportunities you expect to have, and that's harder to pin down. Opportunity volume trends over the last year or two (including seasonality), plus other factors like how much you plan to spend on marketing and advertising and how much bandwidth your salesperson/team has, can all shape how many opportunities you should expect. 

What has to be in place to have it. A defined sales process where every opportunity gets logged in your CRM and closed out as won or lost, so the win rate comes from actual records rather than memory. That also means agreeing on what counts as an opportunity in the first place (sales stage definitions). If one person logs every intro call and another only logs deals once a proposal goes out, your win rate is measuring two different things.

# Time to close (deal velocity)

What it is. The average time from when an opportunity is created to when it's closed-won. Like win rate, you want this from recent deals, because it changes as your offer, pricing, and buyers change.

Why it matters for planning. Win rate informs how many new biz opportunities you’ll win. Time to close tells you when and that can have a big impact on your revenue schedule. 

Say you're planning to ramp up marketing and advertising in Q1. If your deals take about three months to close, the opportunities that spend generates won't turn into closed-won business until Q2 at the earliest, and you won't be delivering the work (or recognizing the revenue) until then. Knowing your time to close lets you put new revenue in the months it will actually show up, and plan your delivery capacity for when the work is expected to start, instead of assuming it starts arriving the day the campaign launches.

What has to be in place to have it. Date stamps on your sales stages in the CRM, one for "opportunity created" and another for "closed-won" date. With those two dates on every deal, time to close is a simple calculation.

One caution. Most agencies don't close a high volume of deals, and with a small sample, an average can be misleading. One deal that sat for nine months while the client reorganized can drag the number way up. Before you plug the average into your plan, look at the raw data for the last six months to a year and decide whether to exclude outliers. The fewer deals you've closed in that window, the more that one outlier skews the result.

# New business average deal size, by service line

What it is. The average size of a closed-won opportunity for each service line. More useful for planning, though, is what the average monthly revenue is for each new deal during the first 12 months. And like cost of services, you want it by service line.

Why it matters for planning. It lets you estimate how much monthly revenue to expect from each deal, from the month it closes through the end of the fiscal year you're planning. That's what turns a count of expected deals into an expected revenue schedule.

Say you expect a lot of small deals from Service Line A and fewer, much larger ones from Service Line B. Paired with your win rate (how many deals) and your time to close (when they land), average deal size by service line tells you how much each of those deals will actually contribute to next year's revenue. Without it, you're multiplying deal counts by a blended average that doesn't describe either service line.

What has to be in place to have it. Every opportunity in your CRM needs a dollar value and a service line, and those need to be kept accurate through close. To get the 12-month monthly view, you also need to tie closed deals back to the revenue they actually produced. Accrual-based revenue recognition at the project level makes this possible.

# Client revenue retention rate

What it is. The share of this year's client revenue you expect to carry into next year, counting both renewals and expansion within existing accounts. It's the flip side of churn: if you expect to lose 30% of this year's client revenue, your retention rate is 70%.

Why it matters for planning. For many agencies (depending on growth stage), somewhere around 70% of next year's revenue comes from this year's clients, between renewals and expansion. That makes retention the biggest single revenue input in the plan. Put it together with your new-business pipeline, and you've forecast the bulk of next year's revenue.

It's also the fastest way to test whether a revenue target is realistic. Say you retain 70% of this year's client revenue and you expect new business to add another 30%. Next year's revenue comes out equal to this year's. Flat. Any growth on top of that has to come from either keeping more of your existing revenue or closing more new business, and once you see it laid out that way, it gets a lot easier to tell whether a 25% growth target is realistic or not.

What has to be in place to have it. A solid account management process and a client health score that helps you determine, client by client, how likely each account is to stay and how much revenue can likely be expected from it next year.

What really drives this metric is how well you understand your clients’ needs, their budget, who your stakeholder partners are, and where there's room to grow. That knowledge lives with whoever owns the account. A good account management process gets it out of their head and into something you can plan from.

# The baseline, then the vision

These five numbers help you get most of the way to a baseline operating model: what next year looks like if the agency keeps doing what it's doing. 

But the actual plan? That comes from layering the owner's vision on top of it. How aggressively do you want to grow? Which service lines do you want to sell more of? What are you doing to improve delivery efficiency? How much are you planning to spend on marketing and advertising, and how much emphasis are you putting on new business in general? Where will you invest the operating profit? All of those change the picture, and they belong in the model.

The impact of these planned changes is hard to quantify. Some are bets that won’t be as impactful as hoped, but you can document them as assumptions that caused you to shift the forecast from the baseline. Revisit these assumptions in the next planning cycle to assess last year’s performance and improve this year’s forecasting. 

So layer the vision in, but be honest about which parts of the plan rest on your baseline and which parts rest on assumptions about what the vision will produce, that way, when your year starts to drift inevitably from the plan, you can use your newfound knowledge about how good or bad you are at planning to inform the following year's budget cycle.

# A gut-check before you build next year's plan

- Do you know your cost of services as a percentage of revenue for each service line, on accrual-based books?
- Do you know your recent new business win rate at your current pricing?
- Do you know your average time to close, and have you looked at the raw deals behind it?
- Do you know what average monthly recognized revenue is for new business, by service line?
- Can you estimate, client by client, how much of this year's revenue will carry into next year?

If you answered no to more than one and want a second set of eyes on where those gaps are before you lock 2027, that's what our [Agency Diagnostic and Roadmap](https://servicecrowd.io/agency-diagnostic-roadmap) is built for.

1\.  Your agency has multiple service lines when there are distinct revenue streams and cost centers or when the work outputs, ICPs, or resourcing inputs vary significantly from each other. For example, maybe some of the work your agency does targets larger Fortune 500 enterprise companies, while the rest of the work targets small businesses. Those are two service lines that should be measured separately.
