SQL beginner looking for more efficient code

I've got the following that works:

Code:

---

--Retreive Input info------------------------------------------------
DECLARE @InStart datetime
DECLARE @InStops datetime
SET @InStart = '09/09/2005 16:20:00'
SET @InStops = '09/12/2005 16:20:00'
--Declares
DECLARE @MonTable table (Payer_Name varchar(35) NOT NULL, Monday int)
DECLARE @TueTable table (Payer_Name varchar(35) NOT NULL, Tuesday int)
DECLARE @WedTable table (Payer_Name varchar(35) NOT NULL, Wednesday int)
DECLARE @ThrTable table (Payer_Name varchar(35) NOT NULL, Thursday int)
DECLARE @FriTable table (Payer_Name varchar(35) NOT NULL, Friday int)
DECLARE @dayStart datetime
DECLARE @dayStops datetime
--Monday

exec spMT_Get_HTC_InputDates @InStart, 0, 'Start', @dayStart output
exec spMT_Get_HTC_InputDates @InStops, 0, 'Stops', @dayStops output
----Get Data
INSERT INTO @MonTable (Payer_Name, Monday)
SELECT PAYER_ABBR_NAME as Payer_Name, SUM(ACCEPTED) as Monday
FROM SUBMITTER_PAYER_COUNT
WHERE CREATED_DATE >= @dayStart AND CREATED_DATE <= @dayStops
GROUP BY PAYER_ABBR_NAME

--Tuesday
exec spMT_Get_HTC_InputDates @InStart, 1, 'Start', @dayStart output
exec spMT_Get_HTC_InputDates @InStops, 3, 'Stops', @dayStops output

INSERT INTO @TueTable (Payer_Name, Tuesday)
SELECT PAYER_ABBR_NAME as Payer_Name, SUM(ACCEPTED) as Tuesday
FROM SUBMITTER_PAYER_COUNT
WHERE CREATED_DATE >= @dayStart AND CREATED_DATE <= @dayStops
GROUP BY PAYER_ABBR_NAME

--Wednesday
exec spMT_Get_HTC_InputDates @InStart, 2, 'Start', @dayStart output
exec spMT_Get_HTC_InputDates @InStops, 4, 'Stops', @dayStops output

INSERT INTO @WedTable (Payer_Name, Wednesday)
SELECT PAYER_ABBR_NAME as Payer_Name, SUM(ACCEPTED) as Wednesday
FROM SUBMITTER_PAYER_COUNT
WHERE CREATED_DATE >= @dayStart AND CREATED_DATE <= @dayStops
GROUP BY PAYER_ABBR_NAME

--Thursday
exec spMT_Get_HTC_InputDates @InStart, 3, 'Start', @dayStart output
exec spMT_Get_HTC_InputDates @InStops, 5, 'Stops', @dayStops output

INSERT INTO @ThrTable (Payer_Name, Thursday)
SELECT PAYER_ABBR_NAME as Payer_Name, SUM(ACCEPTED) as Thursday
FROM SUBMITTER_PAYER_COUNT
WHERE CREATED_DATE >= @dayStart AND CREATED_DATE <= @dayStops
GROUP BY PAYER_ABBR_NAME

--Friday
exec spMT_Get_HTC_InputDates @InStart, 4, 'Start', @dayStart output
exec spMT_Get_HTC_InputDates @InStops, 6, 'Stops', @dayStops output

INSERT INTO @FriTable (Payer_Name, Friday)
SELECT PAYER_ABBR_NAME as Payer_Name, SUM(ACCEPTED) as Friday
FROM SUBMITTER_PAYER_COUNT
WHERE CREATED_DATE >= @dayStart AND CREATED_DATE <= @dayStops
GROUP BY PAYER_ABBR_NAME

--Join data
SELECT Mon.Payer_Name, Monday, Tuesday, Wednesday, Thursday, Friday
FROM @MonTable Mon
INNER JOIN @TueTable Tue ON Tue.Payer_Name = Mon.Payer_Name
INNER JOIN @WedTable Wed ON Wed.Payer_Name = Mon.Payer_Name
INNER JOIN @ThrTable Thr ON Thr.Payer_Name = Mon.Payer_Name
INNER JOIN @FriTable Fri ON Fri.Payer_Name = Mon.Payer_Name
ORDER BY Mon.Payer_Name

I tried to simplify it doing this, but the SUM function gets confused and totals too much data:

Code:
