Accounts Payable Services & AP Automation Providers in Sioux Falls, SD

Limestone Inc is an outsourced accounting firm based in South Dakota. It works with small and mid-sized businesses that want to hand off their day-to-day financial administration. Its offices are in Sioux Falls, Yankton and Brookings. Bookkeeping, payroll and tax work make up the core of the practice, and handling vendor bills is part of its regular bookkeeping engagements. Buyers looking for an AP provider will find Limestone closer to a full-service local accounting partner than a standalone software vendor.

Accounts Payable and Bookkeeping

Limestone handles payables as part of its ongoing bookkeeping. The same team also categorizes transactions, reconciles bank accounts, manages receivables and prepares financial statements each month. Because one team covers all of this, bill payment, cash records and reporting stay connected. The firm's client center points customers to Bill, an online accounts payable application, for handling payables with the firm. It also links to QuickBooks Online as the shared accounting platform. Limestone is a certified QuickBooks ProAdvisor firm and offers:

• QuickBooks setup and training
• ProAdvisor-level assistance
• Advice on using the software's AI-driven automation tools

For companies hoping to automate more of their AP process, this support may be useful.

Payroll, Tax and Advisory Services

The firm's payroll team can take on payroll from start to finish:

• Running scheduled payrolls
• Direct deposit
• Onboarding new employees and processing salary changes
• Payroll tax filings
• W-2 and 1099 forms
• Remitting wage garnishments
• Time tracking

Clients work with the team through a secure online platform. On the tax side, Limestone prepares business and individual returns, plans taxes throughout the year, manages estimated payments and helps clients deal with the IRS. Its business management offering is presented as an affordable alternative to hiring a chief financial officer. The firm meets with clients on a regular schedule and produces tailored reports covering:

• Budgeting
• Revenue, expense and payroll analysis
• Cost of goods sold
• Cash flow
• Industry KPIs
• Tax projections

It also tracks credit card fees as part of this review. For new ventures, the firm can analyze entity type options, set up accounting systems, evaluate retirement plans and support startups as they launch.

Industries Served

Limestone states that it serves several types of clients:

• Construction professionals
• Service-based businesses
• Professional service providers
• Nonprofit organizations

Construction firms and nonprofits often have complex vendor and grant-related payables. For these clients, a bookkeeper who already knows the organization's books can simplify bill approval and payment.

Team and Locations

The firm's website lists a team of eighteen staff members. The Sioux Falls, Yankton and Brookings offices are open on weekdays, giving clients in eastern South Dakota in-person access to the team. Limestone also offers video meetings through Zoom for clients who prefer to meet remotely. The firm describes its purpose as bringing peace, hope and efficiency to business owners.

For buyers, its main appeal is a combination of local offices, QuickBooks certification and a cloud AP workflow built on Bill, all under one provider that also covers payroll and tax.

McGinnis and Company, PC is a certified public accounting firm based in Sioux Falls, South Dakota. It serves individuals as well as owners of small and midsize companies. Its clients come from the city, nearby communities, and some areas of Minnesota and Iowa. The firm does not advertise a dedicated accounts payable service or an automation platform for invoices.

Organizations researching this category would look to its bookkeeping, small business accounting and QuickBooks work for everyday handling of vendor bills and the records that go with them.

Services relevant to accounts payable

The firm's business-side offerings cover much of the routine financial work that keeps payables orderly. They include:

• Bookkeeping and small business accounting
• QuickBooks setup, training and ongoing support
• Cash flow management
• Payroll services
• Financial statement preparation
• Internal controls guidance
• Part-time CFO services
• Audits, reviews and compilations

For a business that runs its books in QuickBooks, a single outside team could assist with several practical needs:

• Setting up the software to suit the company
• Teaching employees how to use it
• Monitoring money leaving the business
• Examining whether approval and payment steps have sensible safeguards

Beyond these, the firm provides strategic and succession planning, assistance with starting a new business, and a complete set of tax services for companies and individuals.

Industries and approach

The firm reports frequent work with restaurants, construction businesses and retailers. Such sectors often deal with a steady stream of supplier invoices, subcontractor charges and inventory purchases. The team also says it keeps current on tax rules specific to an industry at the local, state and federal levels.

McGinnis and Company says it avoids one-size-fits-all service and instead shapes its work around each client and that client's comfort level. Clients are invited to ask questions and share concerns. When someone calls, a CPA answers directly. The firm is willing to meet at a client's home or workplace, and an initial consultation carries no fee.

Background and credentials

The firm has worked in the Sioux Falls area for many years, and each of its CPAs holds a current South Dakota certificate. Rodney J. McGinnis earned his CPA license in 1979 and has over three decades in tax and accounting work. He previously held leadership roles in both the state CPA society and the national AICPA, and he has sat on boards for several nonprofits as well as a family business council in the state.

Patrick J. McGinnis came aboard in 2004. He earned an accounting degree from the University of St. Thomas in St. Paul in 2002 and later completed an MBA at the University of Sioux Falls. He belongs to the state society and the AICPA.

The office is near 2nd Avenue and East 14th Street, close to a local grocery store and easy to reach from SD Highway 42. Clients can share documents through an online portal and a secure transfer tool.

Companies seeking fully outsourced payables processing or invoice automation software should confirm the exact scope with the firm. Smaller organizations that want a local CPA overseeing bookkeeping and QuickBooks-based bill tracking may find it a practical match.

Premier Business Services, which also appears in listings as Premier Bookkeeping & Business Services, Inc., is a bookkeeping and payroll firm based in Sioux Falls, South Dakota. Its website describes the firm as offering bookkeeping and payroll nationwide, so clients outside South Dakota can use it too. Its main clients are small and growing businesses that want to hand off routine financial work to an outside team instead of hiring in-house accounting staff.

Accounts payable and bookkeeping services

Accounts payable is one of the core services on the firm's bookkeeping menu. For buyers comparing AP providers, this means bill tracking and vendor payment work are handled together with the rest of the books, not as a separate product. The firm presents its services as dependable and budget-friendly, and its stated goal is to make clients' finances simpler so owners can concentrate on running their companies. Its published services include:

• Accounts payable and accounts receivable
• Payroll processing and payroll tax filings
• Sales, use and excise tax reporting
• Customer invoicing
• Bank reconciliations
• Financial statement preparation
• Year-end W-2 and 1099 forms
• Budgeting
• Secretary of State filings

Because AP sits next to payroll, reconciliations and 1099 preparation, a client can have one provider manage both paying vendors and the year-end reporting tied to those payments. That can suit companies that pay a lot of independent contractors or that need their payables matched against bank activity every month.

How the firm works with clients

The firm offers outsourced, hands-on service rather than selling its own software platform. Public business listings say it helps small businesses with many administrative needs, from writing sales letters to running payroll and preparing financial statements. The same listings mention work on operational efficiency, expense reduction, process improvement, software conversions, temporary and special assignments, and electronic document storage.

Businesses moving to a new accounting system or reorganizing their payables workflow may find these extras useful. The firm also lists business start-up and organizing support, which can help a new company set up AP and payroll procedures from the beginning. Some listings also mention help with household and personal finances.

Background and credentials

Public listings give 2015 as the firm's founding year. The Better Business Bureau shows it as accredited since 2017 with an A+ rating. A business profile describes it as a Sioux Falls-based financial partner for startups, expanding companies and businesses with seasonal swings in revenue. Its listed office is on South Cliff Avenue in Sioux Falls. It has a small team, which may appeal to owners who want to work directly with the people keeping their books.

For South Dakota buyers, Premier Business Services fits best as a local outsourced bookkeeping partner that includes accounts payable in a broader set of payroll, tax and reporting services. It is not a standalone AP automation software vendor. Companies that mainly want invoice-capture or payment-automation technology should confirm which tools the firm uses before signing on.
