Running a plumbing business means juggling crews, parts, schedules—and finances. The right accounting keeps jobs profitable and cash steady. Below are the seven mistakes we fix most for contractors, with quick remedies you can implement today. If you’re based in Zephyrhills, Wesley Chapel, or nearby Pasco County, our Bookkeeping for Contractors and Controller/CFO Services are built for trades like plumbing.
1) Missing or ignored receipts
Lost receipts = lost deductions and messy audits. Use a mobile capture app and a weekly receipt inbox. We standardize this inside our bookkeeping plans.
2) Underestimating project costs
Low bids can drastically reduce profit margins and may even put the overall financial stability of a project at serious risk. It is absolutely essential to carefully and meticulously track every single cost involved, including the cost of materials, labor hours, drive time, and all overhead expenses tied to each specific job. By utilizing detailed estimates versus actuals reports, businesses gain the ability to accurately compare their originally projected costs against the real, incurred expenditures. This thorough comparison plays a critical role in helping businesses fine-tune their pricing strategies, ensuring that their bids remain both highly competitive in the market and profitable enough to sustain long-term success.
3) Incorrect job costing
If labor, parts, and overhead aren’t allocated to the right job, your P&L lies. We map your chart of accounts to accurate cost codes and create job-cost dashboards via Consulting.
4) Mixing personal and business accounts
Co-mingling spending blocks often results in cluttered and confusing financial reports, which can significantly complicate and lengthen the entire process of tax filing. To prevent these problems from arising, it is strongly recommended to open separate checking and credit card accounts that are specifically designated for different types of expenses. Furthermore, it is absolutely essential to consistently and diligently reconcile these accounts every single month to ensure that your financial records remain clear, well-organized, and easy to manage. Adopting this practice not only streamlines your bookkeeping efforts but also greatly aids in maintaining accurate and reliable records for tax purposes, financial analysis, and overall budget management.
5) Weak time & materials tracking
Missing time entries and unbilled parts can have a major negative impact on overall profit margins, significantly reducing the financial health of a business. To maximize profitability and ensure every dollar earned is accounted for, it is crucial to use consistent item codes across all records and documentation. This consistency helps maintain clear and accurate tracking of resources and costs. Additionally, it is important to require technicians to log their time on the very same day the work is performed, as this practice greatly improves the accuracy and reliability of the recorded information. To further strengthen the process, implement a systematic review of work orders on a weekly basis. This regular review allows any discrepancies, omissions, or errors to be identified and corrected early, ensuring billing remains precise and up to date at all times.
6) Untracked subcontractor payments (1099)
Pay subs without W-9s and you risk penalties. Centralize W-9 collection, track 1099 totals, and prep forms on schedule with our Tax Preparation & Planning.
7) Tax surprises and missed estimates
Quarterly estimates smooth cash flow and avoid penalties. We forecast tax with a rolling 13-week cash-flow plan through Controller/CFO.
