Accounts Payable Services & AP Automation Providers in Lowell, MA

Mill City Accounting Services LLC is a small accounting and tax practice in Lowell, Massachusetts. It supports local small businesses with bookkeeping, payroll and tax work, and it also prepares returns for individuals. Anyone comparing providers for accounts payable should understand that Mill City is a hands-on, people-driven bookkeeping firm. Vendor bills and payables are handled within a broader bookkeeping relationship, and the firm does not offer a software product or an automated payables tool.

Accounts payable and bookkeeping

Bookkeeping is delivered as compilation work, which can be scheduled monthly, quarterly or annually. Clients select the rhythm that matches their volume of transactions and their need for reports. Payables are managed together with receivables, so an owner has a single outside resource watching what the business owes its suppliers and what customers still owe the business. The arrangement suits companies that want dependable, up-to-date records without building a finance department of their own.

Beyond payables, the practice covers many of the recurring accounting and compliance duties a small company faces:

• Bookkeeping compilations, including both payables and receivables
• Payroll processing every week or every other week, along with the required federal and state tax filings
• Business tax preparation for corporations, partnerships, single-owner LLCs, nonprofits and fiduciary filings
• Personal income tax returns, including the state filings that go with them
• Tax planning that forecasts future liabilities
• Consulting for new businesses, such as forming entities, drafting operating agreements, filing annual reports and applying for tax identification numbers
• Notarization by a notary licensed in Massachusetts

Background and experience

The firm was launched in the spring of 2018 by Scott Marchlik, who still operates it. He earned a bachelor's degree in business administration from the University of Massachusetts Lowell in 2007, with a concentration in accounting. That summer he took a staff accountant position at a CPA firm in Cambridge.

He started out as a bookkeeper and gradually moved into preparing taxes for businesses and individuals, and he was an accounting supervisor when he left to go out on his own.

During those years his main clients were owners of quick-serve restaurants and owners of rental real estate. Both kinds of business generate steady vendor activity and ongoing bookkeeping demands, which makes orderly payables especially valuable.

Working with clients

Mill City recognizes that every business and family has its own accounting needs. Prospective clients describe their situation and concerns through an online inquiry form, and the firm replies as soon as it can. The office keeps weekday daytime hours, with Saturday meetings available by appointment. It now operates from Kearney Square in Lowell, having left its earlier Central Street space at the start of 2025. Current clients can settle their invoices online through the website.

For buyers focused on payables, the firm's appeal lies in having vendor bills recorded by the same small team that handles payroll, tax returns and planning, so the tax consequences of everyday transactions are understood. It is best suited to owner-run businesses, particularly restaurants and landlords, that prefer personal local service over an automated platform.
