eCheckDirect
SMBSoftware for accepting checks by phone, fax, or web and printing checks on blank check stock.
Delivery status capture tied to each check authorization record and its fax transmission log.
eCheckDirect is designed for check by fax execution where payment teams need to transmit authorization documents with consistent formatting and traceable handling. The workflow emphasizes check image transmission, failed transmission handling, and a fax transmission log that records what was sent and what delivery status occurred. Authorized signer controls pair approvals with the transmission record to reduce mis-sends and support later investigation.
A tradeoff appears in operational dependency on fax-grade document quality because optical readability affects downstream acceptance. Teams that must send check authorization outside standard ACH adoption tend to use eCheckDirect when banks or counterparties accept faxed check authorization and require clear check images.

How to Choose the Right check by fax software
Check by fax software sends faxed check authorization and check image packets from accounts payable workflows and keeps delivery traceability attached to each outgoing authorization. This guide covers eCheckDirect, CheckMagic, iFax, PaySimple, CheckWriter Pro, MyFax, Fax.Plus, CheckWriter, Q-Check, and CHAX.
The deciding factors are transmission logging tied to each authorization record and the way delivery outcomes connect to approval actions, resends, and exception handling. Teams also evaluate how much workflow automation and access governance the faxing layer provides versus relying on external approval systems.
Fax-to-check workflow features that connect approvals to delivery
The most valuable check-by-fax capability is traceability from each submitted check authorization record to a fax delivery outcome and a fax transmission log. This traceability determines whether exceptions, resends, and sign-off evidence remain tied to the correct check packet.
Teams also need workflow features that prevent approvals from drifting away from what actually left the fax queue. Tools differ in how delivery status is linked to authorization actions, how failed transmissions trigger resend decisions, and how much control the fax layer offers for routing consistency.
Authorization-linked delivery status and transmission logs
eCheckDirect ties delivery status capture to each check authorization record and its fax transmission log. CheckMagic maintains fax job delivery confirmation with a maintained fax transmission log for finance reconciliation.
Fax job tracking tied to delivered check-image packets
iFax links delivery confirmations and transmission failures to each submitted check-image packet. Q-Check links approval status to each outbound check authorization request with job-level tracking and a per-authorization transmission log.
Authorized signer controls connected to outgoing transmissions
eCheckDirect links authorized signer controls to approval actions tied to specific outgoing transmissions. MyFax ties delivery confirmation and fax transmission logs to each authorization send for audit-focused exception handling.
Failed transmission handling that supports resend decisions
CheckMagic provides automated retry handling for failed transmission outcomes alongside delivery confirmation. CheckWriter Pro reports delivery status to support resend decisions after failed transmissions.
Fax-first workflow specificity versus fax as a generic layer
PaySimple uses authorization workflow states and exception handling tied to each transmitted check image instead of a generic fax inbox. Fax.Plus provides transmission outcomes and failure status tailored to faxed check image authorization runs with fewer orchestration details inside the workflow.
Check image generation and dispatch coupling
CheckWriter Pro generates check images directly and ties generation to fax submission to reduce manual formatting. MyFax does not provide built-in MICR encoding or check printing tooling for issuance.
Choose by how the fax layer maps approvals, sends, and exceptions
A good selection starts by matching the fax tool to how the payment approval workflow already operates. The key question is whether approval actions, authorization packaging, and outgoing fax transmissions share the same unit of record and the same delivery evidence.
Next, teams compare how much orchestration and automation is built into the faxing product versus handled upstream in external payment, accounting, or treasury systems. The tools below vary sharply in automation depth and how reliably they maintain routing rules across users and destinations.
Verify delivery evidence is attached to the same record as authorization approval
Select a tool that connects delivery confirmation to the authorization unit of work so finance can reconcile exceptions without guessing which packet failed. eCheckDirect ties authorized signer actions to specific outgoing transmissions with per-authorization transmission logs, while iFax ties job-level delivery and failure visibility to each submitted check-image packet.
Decide whether resend behavior is automated or operational
If resend handling must be driven automatically by fax outcomes, prioritize tools with explicit retry handling for failed transmission outcomes. CheckMagic includes automated retry handling for failed transmission outcomes, while Fax.Plus emphasizes clear delivery confirmation and failure status with less rich fax-to-check orchestration.
Match routing and role complexity to setup tolerance
If multiple users and destinations require consistent routing rules, choose a tool that supports controlled configuration and repeatable packet handling. iFax requires careful setup for consistent routing rules across users, while MyFax focuses on authorization send audit logs and manual approval steps.
Choose between fax-first check-image intake and external generation
If check image generation must be part of the same flow as fax submission, choose an option that couples generation to dispatch. CheckWriter Pro ties built-in check image generation directly to fax submission, while eCheckDirect centers traceability for authorization records and transmission logs regardless of upstream generation.
Assess automation depth for bank file and treasury-adjacent workflows
If bank file automation and treasury management workflows are expected to work through the fax layer, prioritize tools that provide deeper automation surfaces. iFax is limited in bank file automation compared with treasury-focused suites, while CheckWriter Pro has limited API and deep accounting integration options compared with fax-focused competitors.
Common failure modes when buying check-by-fax software
A frequent mistake is selecting a fax tool that logs send activity without tying delivery evidence to the authorization unit of work. This breaks reconciliation when multiple check packets are in-flight and only one delivery fails.
Another mistake is underestimating configuration discipline requirements for routing consistency and approval coordination. The tools with deeper control at the fax layer still require consistent routing rules and predictable packet formatting to avoid misclassification of failed or delivered events.
Assuming generic fax job logs are enough for audit-grade reconciliation
Require delivery confirmation and a fax transmission log tied to each authorization record, such as eCheckDirect or CheckMagic, instead of relying on inbox-style activity history.
Overlooking how inconsistent scans can affect intake and readability
eCheckDirect flags that document readability requirements can slow intake when scans are inconsistent, so standardize scan quality and packet formatting before rollout.
Choosing a tool that cannot map approval coordination to fax send outcomes
CheckMagic notes approval coordination is limited to the integration layer instead of built into faxing, so confirm the approval workflow can still attach to fax outcomes end-to-end.
Underestimating operational overhead from recipient management changes
CheckWriter Pro warns that fax recipient management adds clerical overhead when destinations change frequently, so validate destination churn volume and onboarding workflow.
Expecting bank file automation through a fax-first product
iFax states its bank file automation depth is limited compared with treasury-focused suites, so do not assume the fax layer will replace treasury integrations.
