Build Your First Budget with Auto-Budget Methods

Create your first budget in Fintra using auto-budget methods - prior year, seasonality, driver-based, and percent of revenue - plus multi-year planning basics.

A budget you never build helps nobody, and a budget that takes three weeks to build gets built once and abandoned. Fintra’s budgeting module splits the difference with auto-budget methods: you pick a method per account (or account group), the engine drafts the numbers from your actuals and drivers, and you spend your time adjusting the lines where judgment matters.

This page covers building the first annual budget for a company with at least a few months of actuals in Fintra. If your books are brand new, budget top-down from your operating plan for the first quarter, then rebuild with these methods once actuals exist.

The auto-budget methods and when to use each

Each account line in a budget can be filled by a different method. Choosing the right method per line is 80% of budget quality.

Method	How it fills the line	Best for
Prior year (+growth)	Copies last year’s actuals per month, optionally scaled by a growth percentage	Stable costs: rent, insurance, software, salaries you expect to keep
Seasonality	Learns the monthly shape from historical actuals and applies it to your annual target - the total is yours, the curve is history’s	Revenue and costs with a real seasonal pattern (retail, services with busy seasons)
Driver-based	Computes the line from a driver you plan: headcount × cost per head, customers × price, jobs × materials per job	Anything that scales with a plannable quantity - payroll taxes, materials, commissions
% of revenue	Sets the line as a fixed percentage of the budgeted revenue line, month by month	Costs contractually or empirically tied to revenue: merchant fees, commissions, some COGS
Manual	You type the numbers	One-offs and step changes the history cannot know: a new lease, a planned hire, a marketing push

Auto-budget methods

Building the budget

From empty to approved draft

1
Create the budget
Name it (e.g., "FY2027 Operating Budget"), pick the fiscal year and granularity (monthly is the default that makes BvA useful), and choose whether it spans cost centers/departments.
2
Budget revenue first
Everything else keys off revenue. Use seasonality against your annual target if you have a year of history; driver-based (customers × average contract) if your pipeline supports it.
3
Auto-fill expenses
Apply methods per line or per account group. Run the auto-fill, then walk the grid month by month for the lines that changed the P&L most.
4
Layer the judgment calls
Override specific cells for known events: the second-location rent starting July, the Q3 hire, the January insurance renewal at the new premium.
5
Review totals and submit
Sanity-check budgeted net income by month against your cash reality, then submit the budget into the approval workflow so the version everyone compares against is a deliberate one.

Multi-year plans and import/export

The multi-year plan extends the same structure across 2–5 years at lower granularity - year one monthly, later years often quarterly or annual, driven by growth assumptions per line.
Excel/CSV import lets you build or adjust the grid offline and bring it back - useful when a board or investor template must be honored. Export goes the other way for anyone who reviews in spreadsheets.
Budgets are versioned via snapshots: take one before big edits and before every approval so "what changed since the board saw it" is a diff, not a memory.
Cost-center budgets roll up to departments and to the company - see Cost Centers & Pivot Reports for the structure.

Hands-on labs

Practice against a realistic scenario. Each lab lists the steps, what you should see, and the checkpoints that confirm you got the same result.

Lab 1

Draft Acme’s FY2027 budget in an hour

Scenario

Acme Services ($1.8M revenue, 12 employees) is budgeting FY2027 at $2.1M with two known changes: a second location whose $4,200/month rent starts in July, and one field technician hire planned for April at $58,000/year fully loaded. You have 18 months of actuals in Fintra.

Steps

1
Create "FY2027 Operating Budget", monthly granularity, fiscal year January–December 2027.
Expected: An empty budget grid appears with your P&L accounts as rows and 12 months as columns.
2
Fill Service revenue with the seasonality method against a $2,100,000 annual target.
Expected: Monthly revenue follows the historical curve (summer months noticeably higher) and sums to $2.1M.
3
Fill Wages with driver-based: current headcount cost per month, plus the new tech at $4,833/month from April.
Expected: Wages step up from April onward by roughly $4,833.
4
Fill Merchant fees as 2.9% of revenue and Commission expense as 5% of revenue.
Expected: Both lines track the revenue curve month by month.
5
Fill the remaining expense lines with prior year + 3%, then manually override Rent to add $4,200/month from July.
Expected: Rent shows the July step; other lines mirror last year’s pattern plus 3%.
6
Review budgeted net income by month, take a snapshot named "pre-approval draft", and submit for approval.
Expected: The budget enters the approval workflow with the snapshot recorded.

Checkpoints - you got it right if…

Revenue sums to exactly $2,100,000 with a seasonal (not flat) shape
Wages and Rent both show visible step changes in the right months (April, July)
Merchant fees and Commission move proportionally with revenue
A named snapshot exists and the budget is awaiting approval

Frequently asked questions

How much history do the auto-methods need?

Prior year and seasonality want at least 12 months of actuals to be meaningful; driver-based and % of revenue work from day one because they use your assumptions, not history. With under a year of data, budget manually or driver-based and rebuild at the anniversary.

Can different accounts use different methods in one budget?

Yes - that is the intended design. Methods apply per line (or per group), so revenue can be seasonal, wages driver-based, fees % of revenue, and rent manual, all in the same budget.

Should I budget monthly or quarterly?

Monthly for the current year - BvA reviews happen monthly, and a quarterly budget makes every monthly variance a guess about phasing. Later years of a multi-year plan can be quarterly or annual.

What happens to the budget when my chart of accounts changes?

New accounts appear as unbudgeted lines (variance = all of actuals) until you add them to the budget. When you split or merge accounts mid-year, adjust the budget in the same change so BvA stays line-comparable - and snapshot before you do.

Can I import a budget my accountant built in Excel?

Yes - export the grid template, have them fill it, and import the CSV/Excel back. Imported cells behave like manual entries; you can still apply auto-methods to other lines afterward.
