Accounts Payable Services & AP Automation Providers in Kennebunk, ME

Overview

Assurance Accounting & Tax Services is a small accounting practice based in Kennebunk, in the southern part of Maine, a short drive from Biddeford. Principal Prudence Duross founded the firm in November 2019. It works with business owners, executives, independent professionals and individual taxpayers who want a local team to handle their books, payroll and tax obligations. According to its website, the firm holds a Maine accounting license and is also registered as an investment advisory firm.

For companies evaluating outside help with accounts payable, note that the firm does not list AP processing or AP automation software as a standalone offering. Its relevance to this category comes from its outsourced bookkeeping and small business accounting work, where staff maintain client books on a recurring basis so owners can concentrate on operations. Buyers who need vendor bill entry, payment tracking or reconciliation of payables within QuickBooks should confirm the scope directly with the firm.

Services for businesses

The firm's business offering runs from day-to-day record keeping through higher-level financial guidance:

• Outsourced small business accounting and bookkeeping on weekly, monthly or quarterly cycles
• Payroll processing for a range of clients
• Part-time CFO support
• Cash flow projections and management
• Strategic and business advisory planning
• Financial planning and analysis for established companies
• Guidance on forming a new business

Tax work is also a large part of the practice. This includes business and individual returns, tax planning, and estate and trust filings. The firm also helps clients dealing with IRS issues, such as payroll tax problems or obtaining their IRS file.

QuickBooks expertise

QuickBooks is a recurring theme on the site. The firm sets up the software for small and mid-sized companies, trains users, and answers questions as they come up. For businesses that manage vendor bills and payments inside QuickBooks, this support can help keep payables records organized and accurate. The firm presents it as general accounting software assistance rather than a dedicated AP product.

Team and industries

The team is compact. Prudence Duross brings more than 25 years of experience advising local individuals and businesses. Her work covers tax preparation and planning, bookkeeping and accounting, and specialized QuickBooks setup and training. Carol McEwen has been with the firm since it opened and serves as bookkeeper and payroll specialist.

She runs payroll for the firm's payroll clients, handles recurring bookkeeping, and assists with returns during tax season. The firm highlights experience with construction companies, dental practices, healthcare providers, hospitality businesses, law firms, manufacturers and real estate clients.

Clients can exchange documents through a secure client portal and file-sending tool. The firm offers an initial consultation at no charge to determine fit. Some Biddeford-area businesses prefer a personal, locally based bookkeeping relationship to a large outsourcing provider or a standalone AP automation platform. For them, Assurance Accounting & Tax Services offers direct access to its principal and a stable small staff.

Overview

MMB MBA, LLC is a small accounting and bookkeeping practice based in Kennebunk, Maine, led by its principal, Michelle McNeil-Brown, MBA. She started offering professional services in January 1998 and has worked with businesses across southern Maine and a number of clients farther afield.

For companies in the Sanford area that need help with vendor bills and payments, the firm offers a personal alternative to a large outsourcing center or a standalone automation product. Payables are handled as part of a broader full charge bookkeeping arrangement, and the principal does the work herself.

Accounts payable and bookkeeping

At MMB MBA, payables are one piece of an end-to-end bookkeeping service that covers the whole accounting cycle rather than isolated tasks. A business that hands over its books can expect payables and receivables to be managed together with the supporting records, so that bills, payments and ledger entries remain consistent with the rest of its finances. A typical engagement includes:

• Handling of money owed to vendors and money owed by customers
• Matching bank and credit card activity against the books
• Preparing payroll information for reporting
• Keeping the main ledger accurate and current
• Closing the books at the end of each month and each year
• Producing financial statements

The stated aim is to keep a client's records ready for an audit or tax filing at any moment. Companies whose books have fallen behind can request a QuickBooks cleanup, in which the firm reviews and corrects the data, reconciles accounts, resolves duplicate or miscategorized transactions and audits the chart of accounts. That groundwork is often needed before payables can be tracked with confidence.

Software expertise

The firm does not sell its own payables platform. Instead it works within the systems clients already use or plan to adopt. Michelle is a Certified QuickBooks ProAdvisor and a Certified Xero Advisor. With QuickBooks, she helps with initial setup, customization, troubleshooting and continuing support, and she offers hands-on training in navigation, invoicing, payroll, bank reconciliations and reporting.

With Xero, she assists businesses moving from another system, configuring the software for the first time, tailoring the chart of accounts, connecting bank feeds and receiving ongoing coaching. This suits owners who want their tools set up properly and their staff able to manage routine entries in-house.

Additional services

Beyond bookkeeping, the practice provides managerial accounting support intended to give owners timely, dependable numbers for decisions, including cash flow monitoring and budget analysis. It also performs forensic accounting, such as fraud examination, litigation support and analysis of financial statements, backed by Michelle's graduate certificate in the subject. She also tutors accounting students one on one, whether they are working through a difficult course or preparing for an exam.

Background and approach

Michelle was raised in Portland and takes a particular interest in the success of her home community. Her clients have ranged from basement or garage startups to established mid-sized companies in many industries.

Her education includes an associate degree in accounting from York County Community College, a bachelor's degree in accounting from the University of Southern Maine, and both a graduate certificate and an MBA from Southern New Hampshire University.

She is due to begin a Doctor of Education program at Capella University in 2026, and the firm is associated with the National Association of Certified Public Bookkeepers. New clients begin with a free consultation covering their needs, goals and budget. Fees vary with the type of work, and the office keeps weekday hours by appointment only.
