The challenge with multiple rehab projects running at the same time is that you need to track payments in two directions. You need to know how much each project cost so you can measure profitability. And you need to know how much each contractor was paid in total across all projects so you can file 1099s correctly at year end. Your accounting software can handle both if it’s set up right.

In QuickBooks, create each rehab property as a separate project or customer. When you pay a contractor, you enter the payment under that vendor’s name and assign it to the correct property. This way the expense shows up under the right project for job costing, and it also accumulates under that vendor’s record for 1099 tracking. One transaction, two layers of information.

Before you pay anyone, collect a W-9. This is the step most real estate investors skip until January when they’re scrambling to file 1099s and realize they don’t have half the information they need. Get the W-9 before the first payment goes out. Store them digitally in a folder organized by year. No W-9, no check.

Pay contractors from one dedicated business bank account. Don’t pay some from a personal account, some with Zelle from a different account, and some with cash. When payments are scattered across accounts, tracking becomes a nightmare. If you’re running multiple rehab projects through different LLCs, each entity should have its own account with its own books.

Keep your chart of accounts structured for rehab work. Break costs into categories that matter for your analysis. Materials, labor by trade, permits, dumpster rental, and holding costs like insurance and utilities during the rehab. When a plumber gets paid, you should be able to see it under both the plumber’s vendor record and the plumbing expense category for that specific property.

Reconcile weekly, not monthly. With multiple projects going at once and contractors getting paid in stages, waiting a full month to reconcile means you’ll forget what certain payments were for or which property they belong to. A quick weekly check keeps everything accurate and catches duplicate payments or coding errors early.

At year end, run a vendor summary report filtered by date range. This shows you the total paid to each contractor across all projects. Anyone who received $600 or more in the calendar year gets a 1099-NEC. QuickBooks can generate these directly if your vendor records are complete with names, addresses, and tax IDs from those W-9s you collected upfront.

Document everything beyond just the payment. Save contractor invoices, scope of work agreements, and lien waivers. If you’re ever audited or if there’s a dispute about work quality, you want a paper trail that connects the payment to the work performed on a specific property. This documentation also supports your cost basis when you sell.

The real cost of not tracking properly shows up in two places. First, you can’t accurately calculate profit per project, which means you don’t actually know if your deals are working. Second, you face IRS penalties for missing or incorrect 1099s. Both are avoidable with a system that’s set up correctly from the start.

If you’re juggling multiple properties and feeling behind on the bookkeeping side, getting help with inventory accounting in Orlando and project-level tracking can save you hours every month and give you numbers you can actually trust when evaluating your next deal.
