How to analyze vendor and category spend as Property Management Founders

Finance & FP&AFor Property Management Founders2 apps11 steps~22 min to set up

You manage 200–400 doors across a mix of residential units and maybe a few small commercial tenants. Your operating and trust accounts run through separate bank accounts — often 3 to 6 of them — and every month you're exporting CSVs from your bank, cross-referencing them against AppFolio or Buildium, and rebuilding a vendor spend summary in Excel to answer basic questions: how much did we pay HVAC contractors last quarter, which vendor are we over-using, and why did our landscaping line jump 40% in October? That rebuild takes 2–4 hours monthly and is usually stale by the time you share it with your business partner or CPA.

Outcome

What you'll set up

A live vendor and category spend dashboard that pulls from all your Plaid-connected operating accounts and updates daily — no CSV exports, no spreadsheet rebuilds

Automatic anomaly flags when any vendor charges more than their normal range, so a $1,800 plumber invoice that should be $300 gets caught before the month closes

Month-over-month category breakdowns across maintenance, landscaping, insurance, utilities, and management overhead — organized the way you actually think about your P&L, not the way your bank categorizes it

The Starch recipe

Apps, data, and prompts

The combination of Starch apps, the data sources they pull from, and the prompts you use to drive them.

Apps used

Transaction Insights Runway Analysis

Data sources & config

Starch syncs your Plaid bank account data on a schedule — transactions, balances, and categories refresh automatically across all connected operating accounts. No QuickBooks or AppFolio export required; Plaid reads directly from the bank. If you want to cross-reference against your AppFolio or Buildium ledger, Starch automates that through your browser — no API needed.

Prompts to copy

Connect all my Plaid operating accounts and build me a vendor spend dashboard. Group transactions by vendor and by category — maintenance, landscaping, utilities, insurance, management fees, and other. Show me month-over-month trends for each category, flag any vendor whose charge this month is more than 50% above their 6-month average, and list every new vendor that's appeared in the last 60 days.

Using my Plaid transaction data, show me my top 20 vendors by total spend over the last 12 months, broken down by month. Flag the three categories growing fastest quarter-over-quarter and tell me which vendors are driving that growth.

Walkthrough

Step-by-step

1 Connect your operating accounts through Plaid — most property management firms have 2–5 accounts (operating, reserve, trust float). Starch syncs all of them on a schedule so every account flows into the same dashboard.

2 Open the Transaction Insights starter app from the Starch App Store. This gets you a working spend dashboard in minutes — you can use it as-is or customize it for property management categories.

3 Describe your category structure to Starch: 'Rename and group my transaction categories to match how I run my P&L — maintenance labor, maintenance materials, landscaping, utilities (split electric/water/gas), insurance, management fees, software subscriptions, and other.' Starch recategorizes your transactions accordingly.

4 Tell Starch which vendors are your regular contractors: 'Flag any charge from HVAC vendors, plumbers, or electricians that's more than 40% above that vendor's trailing 6-month average. Alert me in Slack.' This sets up your anomaly detection.

5 Add a new vendor tracker: 'Show me every vendor that has charged my accounts for the first time in the last 60 days, with the charge amount and date.' This catches unauthorized or accidental charges before they become recurring.

6 Connect the Runway Analysis app and wire it to the same Plaid data. This gives you burn rate and cash projection alongside spend — so you can see not just where money went, but how current spending pace affects how long your operating reserves last.

7 Build a quarterly vendor summary: 'Every quarter, give me my top 15 vendors by total spend, the category each falls into, and what percentage of total operating expense each one represents.' This replaces the Excel rebuild you're currently doing before every owner meeting or CPA call.

8 Set up a maintenance spend tracker by property or building: 'Break down my maintenance vendor spend by property address over the last 12 months. Show me which properties are consuming the most maintenance dollars and which vendors are doing the work.' Starch groups transactions by any dimension you describe.

9 Schedule a weekly summary automation: 'Every Monday at 7am, send me a Slack message with: total spend last week, any anomaly flags, any new vendors, and how this week compares to the same week last month.'

10 If you want to cross-reference against AppFolio or Buildium owner ledgers, tell Starch: 'Log into my AppFolio account, pull the owner ledger report for last month for all properties, and compare the maintenance line items against my Plaid transactions for the same period. Flag any discrepancy over $200.' Starch automates that through your browser — no AppFolio API needed.

11 Fork the Transaction Insights app to create a trust account version: 'Build me a separate dashboard for my trust accounts that tracks security deposit inflows, refund outflows, and current balance per property — and flags any month where outflows exceed inflows.' Trust and operating accounts stay separated but visible in the same place.

Worked example

Q1 2026 vendor spend review — 280-door residential portfolio

Sample numbers from a real run

HVAC contractor (Piedmont Air)	18,400
Plumbing (3 vendors)	11,250
Landscaping (2 vendors)	9,800
Utilities pass-through	7,600
Insurance (2 carriers)	14,200
Software subscriptions	3,100
Management fee draws	22,400
Other / new vendors	4,750

In February, Starch flagged a $2,400 invoice from Piedmont Air on a unit that had received a $310 HVAC service call in each of the previous four months — a 670% spike. It turned out the technician had replaced a full air handler without prior authorization. The anomaly alert surfaced it within 24 hours instead of at month-end close. Separately, the new-vendor tracker caught a $1,200 charge from a pest control company that no one on the team recognized — a duplicate vendor that had been set up by a leasing agent and then forgotten. Over Q1, landscaping spend came in at $9,800 across two vendors: the Transaction Insights dashboard showed the second vendor was handling 30% of the jobs at 60% of the cost, a split the owner had never noticed because vendor totals were always buried in a combined maintenance line in the monthly Excel report. That single comparison is now a standing item in the monthly owner call.

Measurement

How you'll know it's working

Maintenance cost per door per month (target: under $35–$50 depending on asset age)

Vendor spend concentration — percentage of total maintenance spend going to top 3 vendors

Month-over-month change in operating expense by category

New vendor appearances per month (unauthorized or duplicate vendor flag)

Operating reserve runway in months at current burn rate

Comparison

What this replaces

The other ways teams handle this today, and how the Starch version compares.

AppFolio / Buildium built-in reporting

Covers owner ledger and rent roll well but doesn't pull bank transaction data, can't track vendor spend across accounts, and produces static reports you export rather than a live dashboard.

QuickBooks + manual bank import

More powerful for full-accrual accounting, but someone has to do the month-end close before you get accurate category data — you're always looking at last month, not this week.

Excel with CSV exports

Fully flexible but takes 2–4 hours to rebuild monthly, breaks when bank export formats change, and has no anomaly detection or alert layer.

Buildout or property-specific BI tools

Purpose-built for commercial real estate analytics but priced for larger portfolios and require a dedicated implementation — not practical for a sub-500-door shop.

On Starch RECOMMENDED

One platform — transaction insights, runway analysis all running on connected data. Setup in plain English; numbers stay current via scheduled syncs and live agent queries.

FAQ

Frequently asked questions

Do I need QuickBooks or my bookkeeper's involvement to set this up?

No. Starch syncs your data directly from Plaid bank feeds on a schedule. You don't need a QuickBooks export or a bookkeeper to close the books first. The tradeoff is that this is cash-basis visibility from your bank accounts — if you need full accrual accounting with journal entries, that's QuickBooks territory. For watching where vendor dollars are going in real time, Plaid is faster and doesn't require anyone else's sign-off.

Can Starch connect to AppFolio or Buildium directly?

AppFolio and Buildium don't offer a public API that Starch can sync against on a schedule. What Starch can do is automate your browser — log into your AppFolio or Buildium account, pull specific reports, and bring that data back to compare against your bank transactions. It's not a real-time sync, but it works for monthly or weekly reconciliation workflows without any manual export steps.

I have separate trust accounts and operating accounts. Can Starch keep those separate?

Yes. You connect each account through Plaid individually, and you can tell Starch exactly how to treat them: 'Keep my trust accounts in a separate view and never mix those transactions into my operating expense dashboard.' You can also build a dedicated trust account tracker that watches security deposit inflows and outflows separately.

Will Starch store all my bank transaction history?

Starch syncs your Plaid data on a schedule and keeps it in Starch's database for the purposes of your dashboards and automations. It's a live operational data surface, not a long-horizon data warehouse — if you need archived transaction history going back years for audit purposes, your bank or accounting software is still the system of record.

Is Starch SOC 2 certified? I have owners who ask about data security.

Starch is not currently SOC 2 Type II certified — that's worth knowing upfront. If your owners or compliance requirements demand SOC 2, that's an honest constraint to factor in. For most small property management firms using Starch for operational visibility rather than storing sensitive tenant PII, this hasn't been a blocker, but it's your call to make.

What if one of my vendors doesn't show up with the right name in my bank transactions — they show up as some abbreviated code?

Tell Starch: 'When you see a transaction matching the description PDMT AIR SVC, treat it as Piedmont Air HVAC and put it in the maintenance labor category.' You can train the categorization logic in plain language. It's not a rigid mapping table you have to maintain in a spreadsheet — just describe the rule and Starch applies it going forward.
