Accounts Payable & Receivable Management
Accounts Payable & Receivable Management
For business owners who want their financial operations running smoothly without the overwhelm of managing it themselves.
In this engagement, Keystone Numbers takes full ownership of your day-to-day financial operations, managing both accounts receivable and accounts payable. Receipts, records, and financial documents are also collected, organized, and kept audit-ready, with everything structured and prepared ahead of your bookkeeping process.
On the receivables side, that means preparing and sending invoices, monitoring outstanding balances, and following up on overdue payments to keep cash flow consistent.
On the payables side, Keystone Numbers manages outgoing payments, coordinates with vendors, and ensures obligations are met on time.
The result is a seamlessly managed financial foundation that protects your time, maintains your professional reputation, and keeps your business operating with precision.

Each month or quarter, Keystone Numbers categorizes transactions, reconciles accounts, and delivers financial statements so you have a clear picture of your financial position.
Cleanup Bookkeeping

DIY Bookkeeping Check
A one-time, monthly, or quarterly assessment of books you manage yourself. Whether you're working in QuickBooks, Xero, or a spreadsheet, we identify potential errors or misclassifications and share observations worth discussing with your tax professional.
Budgeting & Forecasting
Budgeting & Forecasting
For business owners who are ready to take a more strategic approach to their finances.
In this engagement, Keystone Numbers develops an annual or quarterly budget built around your actual revenue, expenses, and business goals, paired with forward-looking financial projections to help you plan for seasonal shifts, growth initiatives, and major expenditures.
The result is a financial roadmap that brings clarity and intention to business decisions.

Payroll Management
For business owners who are ready to hand off one of the most time-sensitive and high-stakes tasks in their business.
In this engagement, Keystone Numbers manages your entire payroll process through Gusto, ADP, or your preferred payroll provider—calculating employee wages, processing payroll on schedule, ensuring tax withholdings are accurate, and maintaining organized payroll records. Whether you have a team of full-time employees, part-time staff, or a mix of both, every payroll run is handled with precision and discretion so your team is always paid correctly and on time.
The result is a seamlessly executed payroll process that eliminates the risk of errors, keeps you compliant, and frees you from the administrative burden of managing it yourself.

How We're Different
How We're Different
Kristina launched Keystone Numbers in 2025. In her accounting work, Kristina saw a gap: most financial services serve large companies, while small businesses need accessible, everyday support.
Keystone Numbers bridges that gap with flexible, tailored solutions from experienced professionals committed to the highest standards of integrity and compliance.
