Accounts Payable Services & AP Automation Providers in San Juan, PR

Overview

Accounting Specialist Group Corporation (ASGC) is an accounting firm headquartered in San Juan and presented online as Accounting Services Group Puerto Rico. It does not sell standalone software. Instead, it acts as an external finance function for its clients and takes over the daily bookkeeping and accounting work that a company would otherwise staff internally. Its clients are located in Puerto Rico and the mainland United States, and Florida is named specifically among the markets it covers.

Buyers evaluating accounts payable support should think of ASGC as a full outsourced accounting department, not a dedicated AP automation vendor. The firm does not publish a separate payables product or a named AP workflow. Payables fall within the broader bookkeeping and accounting operation it runs for each client, together with ledger maintenance, reporting and compliance tasks.

This model may suit companies that want to hand off vendor bill recording and related bookkeeping as part of a wider engagement. Organizations looking for a self-service AP platform should note that ASGC's offering is delivered as a service.

Services

The firm lists the following areas of work:

• Outsourced accounting, with ASGC operating the company's accounting function as an outside team
• Outsourced bookkeeping
• Tax preparation
• Audit services
• Payroll, listed as an option on its consultation request form
• Accounting consultancy
• Compliance assistance for businesses holding decrees under Act 60 for export services
• Ongoing financial statements, reports and data analysis

How it works with clients

ASGC uses automated accounting tools to keep client books current. Clients have continuous, live visibility into their own financial data instead of waiting for periodic report packages. The aim is to keep financial statements current so that owners and managers can make decisions based on recent figures.

The firm presents outsourcing as a way for a company to move internal resources toward market strategy and growth while an external specialist team carries the accounting workload. It positions this as a more affordable option than building a full in-house department.

Work is handled by a tiered staff. Accounting managers lead each engagement and are supported by senior and junior accountants. With this structure, junior staff can handle routine processing while more experienced professionals keep review and oversight. Prospective clients can request a quote or consultation through the firm's website, and the office keeps weekday business hours on Atlantic Standard Time.

Industries and background

ASGC says its accounting expertise adapts to different sectors. Its portfolio includes franchise organizations, restaurants, builders and contractors, professional service practices and tech companies operating across the island and the mainland. The firm reports more than two decades of experience running accounting departments for businesses, and its office is in the Villa Nevarez area of San Juan.

Its Act 60 support may interest companies that moved operations to the island under the export services incentive and need local bookkeeping combined with decree-related compliance work.

Overview

The firm was started in Vienna, Virginia in 2005, became a Puerto Rico corporation in 2022, and names San Juan as its legal headquarters.

Accounts payable services

For buyers evaluating AP support, the company positions payables as a managed service handled by trained bookkeepers rather than a standalone software subscription. Its staff work inside the client's existing ledger and cover the full payables cycle:

• Receiving vendor bills and entering them with GL, class and job-cost coding
• Three-way matching of invoices against purchase orders and receiving documents
• Scheduling vendor payments by due date, cash position and early-pay discounts, via check, ACH or BILL
• Monthly reconciliation of vendor statements to the AP sub-ledger
• AP aging reports, vendor spend analysis and cash flow projections on request
• Digital storage of bills, sign-offs and payment history for audits and tax season

The firm describes its approach as a blend of automation tools and human processing, and it publishes setup guidance for running payables through BILL connected to QuickBooks Online. Supported platforms for AP work include Xero, both editions of QuickBooks (Online and Desktop), NetSuite, Sage and also Zoho Books.

Payables can be paired with its receivables service so that both inbound and outbound cash are handled by a single team, and related offerings include 1099 filing with W-9 collection, payroll, sales tax filing, bank reconciliation, catch-up cleanup, financial reporting, tax preparation and fractional controller or CFO support.

Industries and engagement model

Its site lists dozens of sectors, with AP-specific experience cited in construction (progress billing and retainage), property management with recurring bills spread over several entities, healthcare, e-commerce, manufacturing, franchises and professional services. It also maintains dedicated pages for restaurants, law firms, HOAs, nonprofits and other verticals, along with specialty software such as Restaurant365, MarginEdge, AppFolio, Yardi and Procore.

Engagements begin with a free consultation, followed by onboarding into the client's cloud software, a review of the chart of accounts and setup of standard workflows. Each client is assigned a bookkeeper plus a supervisor who reviews the output and serves as the main contact.

Plans are hourly and month-to-month, without long-term contracts or setup fees, and accounts remain in the client's name.
